North Gate Boulevard Bridge
Client: City of Colorado Springs, Colorado
Description: RGA provided design and construction management for this design/build project where the construction timeline was controlled by the hibernating Preble’s Jumping Mouse. The bridge is a 126-foot, single-span bridge using BT72 girders and a 103-foot wide concrete deck. The bridge utlizies extensive wingwalls supported on concrete caissons. Since North Gate Boulevard is a major arterial street, the bridge was designed for three traffic lanes in each direction, including sidewalks on both sides. The bridge also carries an 18-inch waterline, a 6-inch gas and an 8-inch pumped sanitary sewer line.

Colorado River Pedestrian Bridge
Client: City of Grand Junction, Colorado
Description: This three-span bridge is 410-foot long and utilized two G68 pre-stressed girders (per span) and a 12-foot wide concrete deck. At each pier, there is a 6-foot radius observation platform on each side of the walkway. There are lights embedded in the rail posts that illuminate the deck without lighting up the entire river. There are single 54-inch diameter concrete caissons drilled to bedrock at each pier and 24-inch diameter caissons at the abutments. The RGA team received an ACI Award of Commendation for the design of this bridge.
