Route 161 Intersection Improvements

Erdman Anthony provided preliminary and final design services for improvements to three intersections along Rte 161, a minor arterial in the City of Caribou's downtown district. These three intersections – Herschel Street/Record Street, Record Street/Hatch Drive, and Prospect/Sweden Street/Hatch Drive –  were a key component of the city's plan to revitalize the downtown area.

Erdman Anthony worked closely with the city, its local residents, and the MaineDOT to develop contact-sensitive designs that improved the safety and operating characteristics of these intersections. Development of this project stemmed from a traffic circulation study completed by Erdman Anthony in February 2003 that analyzed the traffic operations of the eight intersections that made up Rte 161 (a one-way traffic loop) and made recommendations for improvement. Engineering services included level-of-service and traffic accident analysis, signal warrant analysis, conceptual plan designs for all eight intersections sign layouts, and preliminary cost estimates.
