State Highway 7 to be Closed Nightly in Boulder for Bridge Demolition Beginning Sunday

December 14, 2012 - Northeastern Colorado/CDOT Region 4 - The Colorado Department of Transportation (CDOT) will be closing State Highway (SH) 7, also known as Arapahoe Road, in Boulder between 55th Street and 75th Street for four nights beginning this Sunday, December 16 in order to demolish a railroad bridge that is being replaced as part of the SH 7 reconstruction project.

Only local traffic will have access to the highway east of 55th Street to Valtec Lane.

Between 5 p.m. and 5 a.m. Sunday, December 16, and between 8 p.m. and 5 a.m. Monday, December 17, Tuesday, December 18, and Wednesday, December 19, eastbound and westbound motorists on SH 7 must use a detour via 75th Street, Valmont Road, and 55th Street. Delays are expected for traffic using the detour, and CDOT asks motorists to build 10 to 15 minutes of extra travel time during the closures. Bus stops within the work zone will be closed each night, and riders can visit for a revised temporary bus schedule.

The SH 7 project features two distinct sections: Cherryvale Road to Westview Drive, and Westview Drive to 75th Street. For the Cherryvale Road to Westview Drive section, SH 7 will be widened from two to four lanes with either a raised median or a center left-turn lane. From Westview Drive to 75th Street, the project will widen the road to add a center left turn lane and 10-foot shoulders. The railroad bridge near 75th Street will be replaced with wider structures to accommodate the roadway beneath.

New pedestrian facilities to be added will include a multi-use path for the entire project length and a sidewalk from Cherryvale Road to Westview Drive. On-street bike lanes and improved bus stops will also be incorporated.

Concrete Express has been awarded the contract for this $18 million dollar project that is anticipated to finish in mid-2013. Additionally, Xcel, CenturyLink, and the City of Boulder will work in coordination with CDOT for this project.
