A construction project to restore a viaduct that’s part of a main thoroughfare in Provo began Wednesday, but transportation officials say traffic won’t be impacted until later this month.
University Avenue, from approximately 920 South to 400 South, is undergoing reconstruction to get the bridge to current design standards, with the goal of improving visibility for drivers and increasing safety, according to the Utah Department of Transportation’s project website. The bridge spans the Union Pacific Railroad switching yard and the current end-of-line for the UTA FrontRunner network.
The viaduct was originally built in 1966 and has undergone several rehabilitation projects since then. This replacement project, estimated to take two years, will extend the bridge’s service life by about 75 years.
“The project will replace the aging structure with a modern bridge designed to better serve drivers, pedestrians and cyclists,” reads a UDOT statement issued Wednesday.
UDOT crews have begun prep work for the construction project. Traffic impacts won’t occur until late October, when the west side of the bridge is slated for demolition. Reconstruction of the west side of the viaduct will then commence and continue through next year before crews switch their focus to the east side.
Throughout the project, at least one lane in each direction will be open during the day, UDOT said.
“This bridge is a vital connection for both Provo residents and regional travelers,” said UDOT project manager Andy Spencer. “Because of how crucial this road is, the new design will focus on enhancing safety and mobility while creating a more comfortable experience for everyone who uses it.”
New features will include two lanes of travel in each direction; dedicated 6-foot bike lanes in both directions; new, wider 8-foot sidewalks on each side, a 12-foot multiuse trail on the west side, connecting 500 South and 600 South; improved sight lines for drivers; and a 10-foot protective fence over the railroad tracks.
