SH 7, Cherryvale Road to 75th Street

Project Description

CDOT will reconstruct State Highway (SH) 7 in Boulder, also known as Arapahoe Road, from Cherryvale Road to 75th Street. The project will improve the safety and operation of the highway in addition to adding new features for pedestrians. The railroad bridge near 75th Street will also be replaced with wider structures to accommodate the roadway beneath.

The project will feature two distinct sections: Cherryvale to Westview Drive, and Westview to 75th. For the Cherryvale to Westview section, SH 7 will be widened from two to four lanes with either a raised median or a center left-turn lane. From Westview to 75th, the project will widen the road to add a center left turn lane and 10-foot shoulders.

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

The project began January 3, 2012 and is anticipated to last approximately two years. It has an estimated budget of $18 million dollars and the contract has been awarded to Concrete Express.

Xcel, CenturyLink, and the City of Boulder will work in coordination with CDOT for this project.

Project Update

The week of Monday, May 20 from 9 a.m. to 3 p.m. SH 7 will be reduced to one lane in each direction between 75th Street and Old Tale Road so crews can perform utility and minor roadway work.

On Sunday, May 19 at 8 p.m., Arapahoe Road/SH 7 will be closed until 5 a.m. Monday, May 20. The closure date and time may be extended depending on weather. Only local traffic will be permitted on Arapahoe Road/SH 7 between 75th Street and Valtec Lane. The road is being closed for installation of precast panels on the second railroad bridge structure. Due to safety concerns, traffic will not be permitted under the bridge during closure hours. All local emergency service providers have been notified of the closure, and signs will be posted to notify commuters of the closure.

During the work hours of 9 a.m. to 3 p.m. Monday through Friday each week, flaggers will be present to direct traffic. Speeds will be reduced to 25 MPH through the work zone and travelers can expect 15 minute delays during peak travel times and work hours. Motorists are urged to Slow for the Cone Zone and to obey all signs and flaggers.
