The new road Bluffdale
The four miles that opened four months early
The Mountain View Corridor opens through Bluffdale
At seven in the evening on December 19, 2025, UDOT opened four miles of new freeway along the western edge of this city, four months ahead of schedule. It carries two lanes each way, and it brought new wildlife fencing, four miles of twelve foot multiuse trail and five pedestrian bridges with it. UDOT projects it cuts delay on Redwood Road by roughly 75 percent. Here is what actually opened, why it landed early, and what it changed on the ground.

The short answer
Yes, the Mountain View Corridor is open through Bluffdale. Four miles of new freeway along the western edge of the city opened to traffic at seven in the evening on December 19, 2025, four months ahead of schedule, carrying two lanes in each direction between the northern Utah County cities and the south end of the Salt Lake Valley. UDOT projects it cuts delay on nearby Redwood Road by about 75 percent. Just as important to anyone who lives near it, the road came with four miles of twelve foot multiuse trail, five pedestrian bridges over the freeway, and new wildlife fencing. It is not the whole corridor, though, so the rest of this page covers what opened, why it landed early, and what it changed on the ground.
What opened
Four miles of freeway arrived on a Friday evening in December
UDOT opened four miles of new Mountain View Corridor to the public at seven in the evening on December 19, 2025. It is the first section of the corridor built as freeway rather than as the divided arterial the rest of the route has been for years, and it runs along the western edge of Bluffdale at the southern end of the Salt Lake Valley, connecting Herriman and Riverton to Saratoga Springs and Lehi.
The road itself is two lanes in each direction. What came with it matters at least as much to anybody who lives near it: new and enhanced wildlife fencing along the alignment, four miles of twelve foot wide multiuse trail, and five new pedestrian bridges over the road.
Construction started in spring 2024. Getting from bare ground to an open freeway inside twenty one months involved moving more than 1.5 million tons of earth and laying more than 350,000 square yards of pavement, and it finished four months ahead of the published schedule.
Carlos Braceras, UDOT's executive director, framed the opening as relief for drivers in a fast growing part of Utah County rather than as a Salt Lake County project, which is an honest description of who it serves. The traffic it is designed to absorb comes from the south, and the reason Bluffdale notices is that it is the ground the road crosses on the way.
A road that took twenty one months to build changed the western edge of this city more than the previous twenty one years did.
Four months early
Two reasons a state highway job beat its own schedule
Large road projects do not usually open early, so the explanation is worth recording rather than waving at. UDOT named two causes and both are specific to this stretch of ground.
The first was weather. A run of mild conditions let crews work longer into the seasons than the schedule assumed, which on an earthwork heavy job of this size compounds quickly. Moving one and a half million tons of material is a weather bound activity in a way that pouring a bridge deck is not.
The second was land. Early access to ground near the Utah National Guard's Camp Williams, which occupies the southern flank of Bluffdale, let the work start sooner in places than a normal acquisition timetable would have allowed. Camp Williams is usually a constraint on this city rather than an accelerant, so this is an unusual entry in the ledger.
Neither of those is a promise about the next phase. The reason to know them is that they explain why a December date arrived when an April one had been expected, which is why some published maps and directories still show the section as under construction well into 2026.
Mapping applications took months to catch up, and some still have not. A road that opens four months early opens ahead of the data refresh cycles that most navigation apps and printed guides run on. Through the first half of 2026 it was common for a route across the south end of the valley to be calculated as though this section did not exist, which produced longer drives than necessary in exactly the direction the road was built to help. If a navigation app is routing you the long way around the western edge of Bluffdale, check the map rather than trusting the estimate.
What it is meant to fix
A 75 percent cut in delay on Redwood Road, as UDOT projects it
The clearest published number attached to this opening is a projection rather than a measurement, and it is worth stating that way round. UDOT projects that delay on Redwood Road, State Route 68, falls by roughly 75 percent as a result of the new section. The department also expects it to take pressure off I-15 around the Point of the Mountain.
Redwood Road is the reason. For years it has been the default north to south route for everybody moving between the northern Utah County cities and the southern Salt Lake Valley without using the freeway, and it carries that traffic through a series of signalized intersections. A parallel free flowing alternative four miles long takes the through traffic off it and leaves the local traffic behind.
For a household in Bluffdale the practical version is that the two routes now do different jobs. Redwood Road remains the street you use to reach things on Redwood Road. The corridor is the road you use to leave, and the difference between them is largest at the times of day when it matters most.
A projection is not a stopwatch, and the honest position in the first year is that the effect is real and the precise figure is not yet a measured one. If you are weighing an address on the basis of a commute, drive it at the hour you would actually drive it rather than trusting either a projection or a routing estimate.
| Redwood Road, State Route 68 | The new corridor section | |
|---|---|---|
| What it is | A signalized north to south arterial through the middle of the south valley | Four miles of freeway with two lanes in each direction |
| Opened | Long established, and rebuilt in pieces over decades | 7 p.m. on December 19, 2025, four months ahead of schedule |
| What it is for now | Local access to what sits along it | Through traffic between the northern Utah County cities and the south valley |
| The projected effect | Roughly 75 percent less delay, as projected by UDOT | Carrying the traffic that produced that delay |
| On foot or by bicycle | An arterial, and it feels like one | A twelve foot multiuse trail beside it with five pedestrian bridges over it |
| What to do about it | Keep it for errands along its own length | Use it to leave, and drive it at your real commute hour before deciding |
Road facts as published by UDOT at the December 2025 opening, checked September 2026. The 75 percent figure is UDOT's projection for delay reduction on Redwood Road, not a measured outcome, and the department publishes updates as conditions settle.
The part you can walk
Twelve feet wide, five bridges, and open the same evening
The four miles of twelve foot multiuse trail that opened alongside the road is the piece of this project that changes daily life on the western edge of the city rather than the drive time out of it. Twelve feet is wide enough for a bicycle to pass a stroller without either party thinking about it, which is not true of most paths in this valley.
The five pedestrian bridges are the more important number. A new freeway is a barrier by default, and a city that gets one usually loses the ability to cross its own western edge on foot. Five purpose built crossings in four miles works out to roughly one every four fifths of a mile, which is close enough together that the road stops functioning as a wall.
The wildlife fencing runs along the alignment for the obvious reason, and it also fixes where the trail sits relative to the traffic. This is not a scenic ride. It is flat, exposed, entirely without shade and directly beside a working freeway, and it is genuinely useful, which is a different thing.
The other new walking connection at this end of the city is older and easy to overlook. Porter Rockwell Boulevard's bridge opened on August 26, 2022 and completed an east to west route joining I-15, the Mountain View Corridor and Redwood Road across the southern end of the county. The structure is 435 feet long and 65 feet high where it crosses the Union Pacific and UTA railroad tracks and the Jordan River, which makes it one of the longest and tallest of its kind in the state.
It carries a ten foot path along its north side, and that path is the first east to west walking and cycling connection anywhere south of 12300 South. In a city whose main east to west street through the middle is interrupted by railroad underpass work, a second east to west crossing that was built for people as well as cars turns out to be worth considerably more than it looked in 2022.
Taken together, the corridor trail on the west, the Porter Rockwell path across the middle and the Jordan River Parkway on the east give this city three separate paved spines that did not all exist five years ago. The river page covers the third of them and the gap the water comes through.
What comes next
The corridor does not end at the northern edge of this city
Two questions follow this opening and only one of them is Bluffdale's. Both are worth stating plainly so that nobody reads four open miles as a finished route.
The first is the phase to the north. UDOT has announced further work on the corridor beginning at Porter Rockwell Boulevard and running north, and that section is Herriman's ground rather than this city's. It is a separate project with its own limits, its own design and its own timetable, and the Herriman page carries it in full along with the corridor's history through that city. Porter Rockwell Boulevard is the hinge between the two accounts, which is why it appears at the top of theirs and the bottom of this one.
The second is closer to home and a great deal more immediate. While a state highway department was finishing a freeway early on the western edge, the city was taking its own main east to west street out of service in the middle, to build a four lane road under a railroad line that has been in the way since the 1870s. That work continued into 2026. The mover page carries the closure limits, the published detours, the cost and what the pair of them does to an ordinary week.
The two projects are unrelated in every way except the one that matters to a resident: for the moment, this city has a new freeway on its western edge and a severed street through its middle at the same time. The first is finished and the second is not.
One road name, two entirely different projects, and they are easy to conflate. Bangerter Highway's rebuild through South Jordan, which was completed in November 2025 and made that route stoplight free from I-15 in Draper to 4100 South in Taylorsville, is a separate program from the Mountain View Corridor. They are parallel roads with parallel timetables and they were reported in the same season, which is why the two get mixed up constantly in conversation about the south valley. Nothing on this page describes Bangerter, and nothing about Bangerter tells you anything about the corridor.

Quick answers
The new road, answered
The four mile section opened to the public at seven in the evening on Friday, December 19, 2025, four months ahead of its published schedule. It is the first stretch of the Mountain View Corridor built as freeway rather than as a divided arterial, and it connects Herriman and Riverton to Saratoga Springs and Lehi through the southern end of the Salt Lake Valley. Construction had begun in spring 2024.
Four miles of freeway carrying two lanes in each direction. Alongside it UDOT built new and enhanced wildlife fencing, four miles of twelve foot wide multiuse trail and five new pedestrian bridges over the road. The job moved more than 1.5 million tons of earth and laid more than 350,000 square yards of pavement between spring 2024 and December 2025.
UDOT named two reasons. Mild weather let crews work longer into the seasons than the schedule assumed, which matters a great deal on a job dominated by earthwork. And early access to land near the Utah National Guard's Camp Williams, on the southern flank of Bluffdale, allowed work to begin sooner in places than a normal acquisition timetable would have permitted. Together those two produced an opening four months ahead of the published date.
UDOT projects that delay on Redwood Road, State Route 68, falls by roughly 75 percent as a result of the new section, and expects it to relieve pressure on I-15 around the Point of the Mountain. That is a projection published at the opening rather than a measured outcome, so treat it as the department's expectation. Redwood Road remains the route for local access along its own length; the corridor takes the through traffic.
Alongside it, yes. Four miles of twelve foot wide multiuse trail opened with the road on December 19, 2025, and five pedestrian bridges cross the freeway, which works out to roughly one crossing every four fifths of a mile. It is flat, new, wide and entirely without shade, so it is a useful connection rather than a scenic ride. The trail is a UDOT facility, so its rules and any future closures are the state's rather than the city's.
An east to west route across the southern end of Salt Lake County joining I-15, the Mountain View Corridor and Redwood Road. Its bridge opened on August 26, 2022, spanning the Union Pacific and UTA railroad tracks and the Jordan River at 435 feet long and 65 feet high, which makes it one of the longest and tallest structures of its kind in Utah. It carries a ten foot path on its north side, the first east to west walking and cycling connection south of 12300 South.
No. The four miles through Bluffdale are open and complete, but the corridor as a route is not. UDOT has announced further work beginning at Porter Rockwell Boulevard and running north, which is a separate project on Herriman's ground with its own limits and timetable; the Herriman companion covers it. Porter Rockwell Boulevard is the hinge between the two accounts, which is why this page stops there.
No, and this is the most common confusion in the south valley. Bangerter Highway is a separate parallel road on a separate program, and its rebuild through South Jordan was completed in November 2025, making that route stoplight free from I-15 in Draper to 4100 South in Taylorsville. The two were reported in the same season, which is why they get conflated. Nothing about one tells you anything about the other.
Because a road that opens four months early opens ahead of the data refresh cycles that most navigation applications run on. Through the first half of 2026 it was common for a route across the south end of the valley to be calculated as though the section did not exist, which produced longer estimates in exactly the direction the road was built to shorten. If an app is routing you the long way around the western edge of Bluffdale, check the map rather than trusting the estimate.
A new road changes what an address is worth to you, and not always in the direction people assume
Four miles of freeway with a trail beside it and five crossings over it is a genuinely different western edge from the one this city had in November 2025, and it lands differently on a street two blocks away than on one two miles away. Send me the streets you are weighing and a Salt Lake County partner agent will walk the crossings and the frontage with you, while I stay on the file for the homework and the financing side.
