Home / CSAH 12 (Stillwater Road/75th Street) Safety and Management, Washington County, Minnesota
A CSAH 12 concept was developed that met the functional needs of this county highway, while also vastly improving the multimodal environment for pedestrians, bicyclists, and those reliant on ADA-compliant facilities.
The CSAH 12 corridor through the Cities of Mahtomedi, Willernie, and Grant is characterized by two distinct segments–a “small town” downtown area in the west and a more rural, high-speed corridor to the east. The western, urban segment posed multimodal transportation challenges such as discontinuous, non-ADA-compliant sidewalks, pedestrian safety issues, and parking shortages. In addition, local communities sometimes had differing visions and varying abilities to fund potential transportation improvements.
Bolton & Menk worked with Washington County to address the transportation needs along the CSAH 12 corridor. We applied an integrated transportation planning approach to address the safety, operations, and accessibility needs in a manner sensitive to the local context, goals, and financial feasibility. We considered pedestrian and bicyclist needs and connections, existing and planned land uses and corresponding parking needs, and sensitive environmental resources; developed and adjusted concepts to meet the needs of all parties; engaged the public; and helped secure funding.
Bolton & Menk was successful in working with Washington County and the local communities to meet the functional needs of this county highway, while also vastly improving the multimodal environment for pedestrians, bicyclists, and those reliant on ADA-compliant facilities.
