CLIENT'S OBJECTIVES
The Maine Department of Transportation (MaineDOT) hired CLD to perform in-depth alignment and bridge-type studies of replacement alternatives to determine the most cost-effective solution that addresses the complicated design efforts of the area.
THE FACTS
MaineDOT was seeking alternatives for providing adequate travel widths to this existing 150-foot truss bridge on ME Route 23. Many considerations needed to be addressed including the significant amount of truck traffic, sidewalks which carried pedestrians to the Riverwalk, the adjacent Memorial Park, an informal gravel parking area on the east side, a cemetery on the southeast corner close to the existing pavement, a force main sewer line, overhead utilities, hydraulic capacities, and a private residence on the southwest quadrant. In addition, ME Route 23 intersects with ME Route 16 approximately 600 feet north of the bridge, with a steep grade which caused incidents with vehicles during icy storms.
THE RESULTS
CLD is working with the MaineDOT to finalize alternatives and recommendations. Four roadway alignment alternatives were studied with various profiles and bridge types to provide a comparison of costs versus impacts. Each alternative considered improvements to the ME Route 16 intersection to provide a platform for vehicle storage at the intersection. In addition, each alignment was designed to allow for completion of a sidewalk in front of the cemetery, while avoiding impacts. Redesign of the driveways and drainage for the private residence was performed to ensure adequate access to the property. Several alternatives for pathway and parking area reconfiguration were also studied in combination with the roadway alignment. A collaborative effort with Town staff, utility representatives, property owners, concerned residents, and local interest groups has been undertaken to ensure project support and consensus of the selected alternative. The project was taken to a Public Meeting in the Fall of 2002 for final approvals, and is currently under construction (Summer 2005).
