The project is for bridge replacement of two (2) truss bridges. The bridges were built in 1929 and are single lane bridges. The existing bridges create a "bottleneck" and are geometrically obsolete in the sense that they are restricted in width and height. The new bridges are designed with increased width to accommodate two lanes of traffic, increased traffic load, pedestrians, equestrians, and bicyclists. Schedule A: Bridge #1520 (east bridge) crosses Percha Creek. It will be constructed immediately downstream of the existing bridge, and the existing bridge will remain in place. The new bridge will have a curved deck supported by straight precast concrete girders. Length of the bridge will be 115 feet measured along the center line of roadway and will be founded on spread footings with 15-foot approach slab at both ends. Retaining walls will be constructed on the north side of the bridge to eliminate the encroachment on right of way and to retain parts of the historical trail. Option X: The west bridge #1521 crosses Middle Percha Creek. The proposed bridge will be constructed in the same location of the existing bridge and the existing bridge will be removed. NM Bridge #1521 is located on a tangent, will have a length of 103 feet and 6 inches and will be founded on spread footings with 12-foot approach slab at both ends. Specific items of work will include the following: Removal of bridge structure Precast, prestressed concrete girder (NM BT 63); Reinforcing steel Reinforcing steel, epoxy coated Bridge Railing, concrete Structure transition railing Reinforce concrete retaining wall Construct and maintain diversion Safety features
