Midvalley Express

MVX will connect Murray Central station with the West Valley Central station, connecting with the Intermountain Medical Center, Sorensen Research Park, Salt Lake Community College Taylorsville Redwood Campus, and the Calvin Rampton Complex (which houses the Utah Department of Transportation, the Utah Department of Public Safety Driver License Division, and the Department of Technology Services) along the way. About a fifth of the approximately 7-mile (11 km) route will be in dedicated lanes along 4500/4700 South (Taylorsville Expressway/Utah State Route 266) with the other four-fifths running along various city streets. There are fifteen planned stops for the line. It began construction in the Spring of 2024, with construction originally anticipated to conclude during Fall 2026,^[3] but service is expected to start ahead of schedule in April 2026.^[4]

UTA has assigned MVX the route number 50X.

MVX will begin its route at Murray Central station, with its connections to the Red and Blue TRAX lines and FrontRunner at Murray Central station in an expanded bus bay. It will exit at the intersection of Cottonwood Street and 100 West, turning north onto Cottonwood Street. It will continue by turning west onto Vine Street. After crossing over the railroad tracks, it will reach the Vine Street stop on the western side of the intersection with Commerce Drive. From there it will cross over Interstate 15 and turn north onto Murray Boulevard, and reach the Murray Boulevard station at approximately 5030 South. After continuing north, it will use 4800 South/Murray Taylorsville Road to turn west and cross the Jordan River and the Jordan River Parkway Trail.

Upon crossing the Jordan River, MVX will leave Murray and enter Taylorsville. It will immediately turn north onto Sunstone Road, following the road to the northeast and reaching the Sunstone station halfway down the road. At the end of Sunstone Road, it will turn north onto Atherton Drive, where the Monte Vista station is located, at approximately 4595 South. Upon reaching the end of Atherton Drive, it will turn west onto 4500/4700 South and enter the dedicated guideways, in addition to immediately reaching the East Atherton station, the first of three located in the median of the road.

It will continue down 4500/4700 South in dedicated lanes, stopping at the West Atherton and Fore Lakes stations. The guideway ends near Redwood Road (SR 68), after which MVX will continue by turning north onto Redwood Road then west onto Community Boulevard to reach the new transit center in the south east corner of the Salt Lake Community College Campus. From there it will leave SLCC the way it came in in order to continue west on 4700 South. The route will have one more stop in Taylorsville, the 2200 West station.

MVX will leave Taylorsville and enter West Valley by crossing under Interstate 215 and turning north onto 2700 West. The route will continue north on 2700 West, stopping at the 4700 South 2700 West (near the Calvin Rampton Complex), State Complex (serving the state complex and American Express offices), 4100 South, and 3800 South stations. The route will reach its end by turning west onto 3650 South and entering West Valley Central Station, with its connection to the Green TRAX line.

The route from West Valley to Murray is the same with the one exception that the eastbound stop at the east intersection of 4500/4700 South and Atherton Drive is on the side, rather than the median.

A total of fifteen stops are planned for the Midvalley Express.
