St. Peter leverages bridge project to improve business district

A 600-foot section of Broadway Street in the downtown St. Peter, Minn. was reconstructed in 2017 to beautify and strengthen the busy eastern entrance to the downtown business district. downtown. Drivers enter from the historic Highway 99 Minnesota River Valley Bridge and the project extended from the bridge to Highway 169 (Minnesota Street).

Simultaneous projects a sensible move for MnDOT and St. Peter

City leaders seized the opportunity to reconstruct that end of Broadway Street when MnDOT rehabilitated the unique historic Pennsylvania thru-truss bridge; MnDOT was setting up detours the city could take advantage of. The bridge project involved strengthening truss floor beams, constructing a new concrete bridge deck and sidewalk, and more. Some bridge work remains for 2018.

“The city was involved with the design, putting a plan together, and bidding the project,” said City Engineer Jeff Domras, P.E. “We added raised decorative concrete medians, signals, accessible sidewalks and new parking configurations.” The $1.36 million project involved replacing underlying utilities, underground stormwater infrastructure and adding a fiber optic conduit.”

Also, the city sat down with business owners to explain the project and work out a way to minimize the impact on those businesses.

“I think everyone’s very happy with the street,” said Domras. “It was well worth it.”
