Project Overview

The South Pratt Parkway Bridge replacement project was substantially complete in early May 2019.

Bridge users may encounter brief lane closures as crews complete final "punch list" items on and around the bridge.


The South Pratt Parkway Bridge was built in the late 1970s and was approaching the end of its useful life. The bridge was too narrow for the traffic volumes that crossed it daily, classifying it as “functionally obsolete” per the Colorado Department of Transportation's biannual bridge reports.


Although the previous bridge was structurally adequate, upgrades such as expansion joint improvements and guard/bridge rail updates were needed. The new bridge has been widened to safely carry traffic and to provide pedestrian/bike facilities along both sides of this collector roadway, as well as connections to the St. Vrain Greenway trail. In addition, the new bridge has been designed to safely pass 100-year flood flows of the St. Vrain Creek, which the old bridge did not do.

This project was a multi-agency partnership between the City of Longmont, the Federal Emergency Management Agency (FEMA) and the Colorado Division of Homeland Security and Emergency Management (DHSEM).


Funding for this $6.5 million project came from the City's 3/4-cent Street Fund sales and use tax, as well as from a FEMA pre-disaster mitigation grant.
