Bridge Deck Pour to Close Westbound US 285 and Federal Boulevard Tonight

October 4, 2010 - Denver Metro Colorado/CDOT Region 6 - DENVER—Tonight, October 4th, the Colorado Department of Transportation (CDOT) will pour the deck for the new Federal Boulevard bridge over US 285 (Hampden Avenue).

The work will require a full closure of westbound US 285 over Federal Boulevard as well as northbound and southbound Federal Boulevard under US 285.

To complete the bridge work, the following lane closures will be in place tonight:

  • Westbound US 285: Single lane closures will begin at 7 p.m. with all lanes closing by 9 p.m.  Detour: Motorists will be detoured via the on and off-ramps at Federal Boulevard. Uniformed traffic control will be on site to direct motorists through the interchange.
  • Federal Boulevard: One lane of northbound and southbound Federal Boulevard will be closed at 7 p.m. with all lanes closing by 9 p.m. Detour route: Motorists on southbound Federal Boulevard will take westbound US 285 to Sheridan Boulevard where they will return to eastbound US 285 for access to Federal Boulevard.  Motorists on northbound Federal Boulevard will take eastbound US 285 to Santa Fe Drive where they will return to westbound US 285 for access to Federal Boulevard.

Major delays are expected on westbound US 285 as well as Federal Boulevard tonight and alternate routes are strongly advised.  CDOT would like to remind motorists to obey all

construction signs and flaggers and to “Slow for the Cone Zone.”  Fines will be doubled for most infractions that occur in the work zone.  All lanes of Federal Boulevard and westbound US 285 will reopen by 5:30 a.m. on Tuesday.

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

In all, the project will:

o   Reconstruct approximately four miles of US 285 between Federal Boulevard and Kipling Parkway

o   Replace the bridges on US 285 over Wadsworth Boulevard, Pierce Street and Federal Boulevard

o   Add additional through lanes on Wadsworth Boulevard and reconstruct the US 285/Wadsworth Boulevard intersection

o   Rehabilitate the bridge decks on US 285 over Estes Street, Bear Creek, Raleigh Street and Sheridan Boulevard

o   Widen the inside shoulder of US 285 between Wadsworth Boulevard and Sheridan Boulevard

o   Add an additional left turn lane from southbound Knox Court to eastbound US 285

o   Construct drainage and water quality improvements to accommodate potential future widening or other construction projects

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.
