Bridge Girder Installation to Close Pierce Street Under US 285 on Sunday

February 25, 2011 - DENVER — On Sunday, February 27th, the Colorado Department of Transportation (CDOT) will install girders for the final portion of the new US 285 bridge over Pierce Street.

This activity will require a full closure of northbound and southbound Pierce Street under US 285 as well as a single left lane closure on eastbound westbound US 285 near Pierce Street.

“This is the final set of girders to be installed at Piece Street as well as on the entire project,” said CDOT Project Engineer Kevin Sullivan.  “We still have a few more major bridge activities left in the project, but we are making great progress.”

To complete the girder installation, one lane of eastbound and westbound US 285 will be closed at 7 p.m. and the full closure of Pierce Street under US 285 will begin at 9 p.m.  All lanes of US 285 and Pierce Street will reopen by 5:30 a.m. on Monday.

During the closure of Pierce Street, detour routes will be in place:

  • Southbound Piece Street Detour: Motorists on southbound Pierce Street will take westbound Hampden Frontage Road to southbound Wadsworth Boulevard where they will return to eastbound on the West Hampden Frontage Road for access to Pierce Street.
  • Northbound Pierce Street Detour: Motorists on northbound Pierce Street will take westbound West Hampden Frontage Road to northbound Wadsworth Boulevard where they will return eastbound on West Girton Avenue and south on South Vance Street to Hampden Frontage Road for access to Pierce Street.

CDOT would like to remind motorists to plan ahead, obey all traffic signs and flaggers and to “Slow for the Cone Zone.” Fines for most infractions that occur in the work zone will be doubled.

The girder installation is part of a safety and mobility improvement project on US 285 between Federal Boulevard and Kipling Parkway.  The $40.1 million design-build project will reconstruct US 285 and replace three bridges among other improvements.

Concrete Express Inc. and Tsiouvaras, Simmons, and Holderness, Inc. is the design-build team for this project that will be completed by the end of June 2011.
