WisDOT | Seven Mile Road Interchange, Pedestrian Beacons
- Electrical Engineering
SINGH was selected to provide investigation and design for Rectangular Rapid Flashing Beacons (RRFB) as a part of a change order to the North-South IH-94 Corridor Reconstruction Mega-Project by the Wisconsin Department of Transportation (WisDOT). As part of the larger corridor reconstruction, the Seven Mile Road Interchange was undergoing realignment and relocation of frontage roads to allow for a new diamond interchange. The relocated frontage roads separated the Seven Mile Fair facilities from parking areas serving the fair. The new arrangement resulted in unsafe crossing for a high volume of pedestrians crossing a wider Seven Mile Road and newly constructed frontage road.
SINGH assessed the project site and provided final design for the Rectangular Rapid Flashing Beacons for the crosswalk facilities located at the Seven Mile Road Interchange. These unique crosswalk warning systems present a higher warning level to drivers that pedestrians are present. SINGH provided design coordination with Prime Engineering Project Team to address required geometric changes to accommodate the modified crosswalks.
Due to the remote location of the Seven Mile Road RRFB crosswalks there was no convenient existing power source for the RRFB and street lighting. SINGH investigated alternatives and provided design for the WisDOT preferred alternative or solar powered beacons and street lighting for the pedestrian crossings.
Seven Mile Road represents the first solar powered lighting WisDOT has implemented in the state of Wisconsin.
