About this file
This is a historical drawing index and culvert profile document prepared by the Connecticut Department of Transportation for the rehabilitation of Bridge No. 06770, an unnamed brook crossing on State Route 796 (Milford Parkway Extension) in Milford, Connecticut. The project involves the rehabilitation of an existing culvert with proposed liner pipe installation. The document contains seven sheets of historical and technical drawings, including highway plans, cross-sections, and culvert profiles, with drawing dates ranging from June 23, 2025 to May 30, 2026. All drawings are marked as "For Information Only," indicating this is reference documentation rather than construction specifications.
The technical drawings document existing conditions and proposed modifications to the culvert system. The existing culvert has varying slopes, with the proposed liner pipe designed in multiple sections with different diameters (4'-6" and 4'-9") and slopes (ranging from 7% to 22%) to accommodate placement within the existing pipe structure while allowing space for grouting. The profile analysis incorporates survey data from inlet and outlet elevations, 2020 and 2021 inspection reports, and SLAM scanner data. The drawings note that the liner pipe may not be able to maintain a constant profile due to the variable slope of the existing pipe, and the document includes notes addressing data discrepancies between inspection methodologies and survey information used to develop the proposed rehabilitation design.
