The Matanuska-Susitna Borough (MSB) is seeking engineering consulting services for design and construction management to replace the existing Kepler Drive bridge over the channel connecting Kepler and Bradley Lakes with a culvert. The Kepler Drive Bridge is located near milepost 37 of the Glenn Highway south of Palmer, Alaska, within Road Service Area 16 (South Colony) and serves public and private property, including a campground for recreational vehicles. The bridge is in poor condition, and the foundation is believed to be settling due to the construction of the bridge’s spread footings on compressible soils. As a result, the bridge causes vehicles to “bottom out” and recreational boats crossing below the bridge have insufficient clearance to travel safely between lakes. The intent of this project is to remove the 20+ year-old timber bridge and replace it with a large-diameter arch-pipe, box culvert, or similar structure. The proposed upgrade shall be wide enough to accommodate a single lane of traffic for a local road (typically 10 feet), including minimum 2-foot shoulders and a 5-foot-wide pedestrian walkway on the west side of the bridge. The culvert shall have a foundation suitable for the soil conditions and shall be built with sheet pile or concrete headwalls to minimize wetland impacts and have timber rails to match the park aesthetic. The walkway should be delineated by a concrete curb stop, rail, or similar device to provide protect pedestrians fishing on the bridge. The proposed culvert shall provide a minimum of 5 feet of freeboard above the channel’s ordinary high-water line to allow for recreational boat traffic to pass safely
