Featured Projects

North Shields Road and Bridge Improvements

Client: Larimer County

Our Interwest team provided Civil Design Engineering for this ¾-mile-long arterial roadway project which also addressed multiple access and safety issues along this busy corridor. The project for Larimer County included challenges like widening the roadway adjacent to private property features, adding bicycle and pedestrian facilities (bike lanes and sidewalks), providing improved access to and from parking for the Poudre River Trail, as well as replacing the existing structurally deficient bridge over the Cache la Poudre River.

North College Avenue Corridor Improvements

Client: City of Fort Collins

Our team at Interwest contributed to this very high profile and constrained project which addressed improvements to the ‘Northern Gateway’ of the City of Fort Collins. This project included multiple challenges like significant access control definition and consolidation, as well as improving safety for motorists, pedestrians, cyclists and transit users, utility coordination, and incorporating urban design and landscape features. Comprehensive and detailed phasing and traffic control plans were essential, as was extensive communication with the Colorado Department of Transportation (CDOT), project stakeholders, and affected business and property owners along the half-mile corridor.
