Clearfield FrontRunner Station Construction


Station Boulevard connects State Street to the Clearfield FrontRunner Station. Additionally, Station Boulevard provides new access to parking and the pick-up/drop-off area at the station. Additional access points and new roads will be completed this summer.

The Utah Transit Authority (UTA), in conjunction with Clearfield City, is developing a mixed-use master development project at the Clearfield FrontRunner Station. This type of project is often referred to as a transit-oriented development or TOD.

Currently, construction and installation of infrastructure and utilities is underway. Upon completion of critical utilities and infrastructure, development of the site will begin. During the construction phases, it will be necessary to have temporary parking and vehicle/pedestrian access. These accesses will be adjusted from time to time depending on construction.

During construction, it is important to follow all signage relative to parking and vehicle/pedestrian access. This is important for your safety.


Provo Pedestrian Bridge Construction

UTA will begin Tiger Project work to relocate some utilities for the new Pedestrian Bridge at the Provo FrontRunner Station. These utility relocations will result in 3 ADA stalls being relocated to the south of the existing stalls (see map below).

Full construction will begin November 1, 2022 and last for approximately 10 months. Majority of the construction will be during the day, but there will be intermittent night work throughout the project. Residents and businesses should expect standard construction noise from equipment and vehicles. For any further questions about the construction please contact Provo City at (801) 852-6000.
