SD FTFW MADI 10(2) & 9000(1) REHAB MADISON WMD HQ ROAD

RFP Description

Location: South Dakota. PROJECT NUMBER: SD FTFW MADI 10(2) & 9000(1) PROJECT NAME: REHAB MADISON WMD HQ ROAD PROJECT DESCRIPTION: The scope of this project includes pavement reconstruction to the approach road and parking lot for the Madison Wetland Management District (WMD) Headquarters and the United States Fish and Wildlife Service (USFWS) Visitor Center. The designed pavement section is proposed to be 3.5 inches of asphalt concrete pavement (ACP) over 4 inches of aggregate base material. The proposed parking lot will be installed at grade with the adjacent sidewalk and concrete trail. The project will improve safety and mobility for staff and visitors by providing improved access to and parking for the Payne Waterfowl Production Area (WPA). The pavement improvements will also extend the service life of the access road and parking lot wearing surfaces. SCOPE OF THE WORK: The existing two-way, single-lane operation of the access road will be preserved by constructing a consistent 14-foot roadway section. Pavement reconstruction will also address the approach road apron on the left side of the roadway between stations 106+02 and 106+74. The project also includes full reconstruction of the existing parking lot and the asphalt apron on its east side, which connects to the concrete trail leading to the visitor centers east entrance. The updated pavement marking layout will provide eight 10-foot by 20-foot parking stalls with one accessible stall on the north side, and ten 10-foot by 20-foot stalls on the south side. The northern edge of the parking area will maintain its existing tie-in elevation with the 6-foot sidewalk, and the parking surface will be regraded to a uniform 1.75% cross slope, removing the existing centerline grade break.
