Platte Avenue Bridge over Sand Creek traffic to be diverted overnight Monday, long term closure at Space Center Drive begins Tuesday

Share this page:

Westbound traffic on Platte Avenue will be diverted onto Galley Road between Wooten Road and the Powers Boulevard interchange from 8 p.m. Monday, Nov. 22 to 5 a.m. Tuesday, Nov. 23. Detours will be in place overnight for westbound traffic. All work is weather and resource dependent.

  • Westbound traffic on Platte Avenue will be detoured onto the northbound exit ramp at the Powers Interchange, then north to Galley Road and west to Wooten Road
  • Southbound traffic on Powers desiring to head westbound on Platte Avenue will detour and exit at Galley Road then west to Wooten Road

This signals the move to phase 3 of the bridge replacement project. During this phase, vehicular and bicycle traffic will be shifted onto the newly constructed mid-section of the Platte Avenue over Sand Creek bridge. Drivers are asked to use caution in and around the area and follow construction signage.

Beginning Tuesday, November 23, a portion of Space Center Drive will be closed at Platte Avenue. The right turn access from Space Center Drive on to westbound Platte Avenue will be closed through Spring 2022. The right turn access from westbound Platte Avenue on to Space Center Drive will continue to remain open.

All business access will remain open throughout construction. Bicyclists and pedestrians are reminded of the restricted access around the site during construction and motorists are advised to take alternate routes when possible. The full project is expected to be complete in May 2022.

This project is replacing the two existing Platte Avenue bridges over Sand Creek with one bridge structure and adding sidewalks along the north and south sides of Platte Avenue over the creek. Construction will also accommodate the future Sand Creek Regional Trail under the bridge. The Platte Avenue bridges, built in 1956, suffered from flood damage in 2008 and have general structure degradation. 

Platte Avenue is one of the city’s main east/west mobility corridors, and the new bridge will accommodate future growth along the corridor by providing additional lanes on Platte Avenue, along with signalizing the intersection at Space Center Drive. The project totals approximately $14 million, funded in part by the Pikes Peak Rural Transportation Authority and a federal grant.
