The City of Boulder Transportation Department collaborated with CDOT on this local agency project to design an impressive new “Gateway” into Boulder. This section of SH 119, also called the Diagonal Highway, used to be in the outskirts of the city, but has become a very busy area with what was a deteriorated asphalt road and no pedestrian or bike facilities in 2015.
To solve this problem Castle Rock Construction managed and built a complex project with an extensive new drainage system, off-street bike lanes, multi-use path, improved transit facilities, various colored concrete aesthetic components, durable concrete roadway, incredible landscape features and art plazas for the community to enjoy. Coordination with the multiple departments within the City of Boulder, CDOT, RTD, contractors on adjacent projects and the 20 subcontractors onsite was key to CRCC’s success on this job.
Some of the unique elements on the Diagonal Reconstruction include:
In order to accommodate the public during construction, lane closures were only utilized during off-peak times throughout the week, bicycle routes for both eastbound and westbound were maintained at all times and intersection reconstruction was limited to weekend work.
The Diagonal Reconstruction project is a compilation of numerous talented contractors coming together to build a job that the people of Boulder and those that visit can appreciate and enjoy for a very long time. We appreciate the City of Boulder and Colorado Department of Transportation’s hard work and innovation on the preparation for and execution of this project.
