📋 Tender Overview
Project No. : ST289 C038EG
Description : The roadway reconfiguration of Douglas Avenue (U.S. Highway 6), between Merle Hay Road and Lower Beaver Road (total length of approximately 10,000 lineal feet), from a four-lane undivided cross section to a three-lane cross section (with center turn lane) is proposed in the Douglas Avenue Corridor Plan. This work includes: -Douglas Avenue reduced to a three-lane roadway between Merle Hay Road and Lower Beaver Road. -Maintaining Douglas Avenue intersection geometry, add/drop lanes at intersections. -Traffic Signal Modifications, including adding flashing yellow arrows and right-turn overlaps where appropriate, coordinated signals with optimized cycle/splits/offsets. The pilot project, completed in 2021, included striping, signing and signal modifications to accommodate the conversion of Douglas Avenue to three lanes between Merle Hay Road and Lower Beaver Road. The Iowa DOT resurfaced Douglas Avenue in 2021 which provided an opportunity to implement the pilot project. The permanent project, anticipated in 2025, would include new pavement and curbs and gutters, sidewalk improvements, a High Intensity Activated Crosswalk (HAWK) beacon for pedestrians crossing Douglas Avenue east of 30th Street, private property impacts and traffic control changes to provide enhanced operational and safety improvements along the corridor.
