Traffic Management Enhancement Phase 5-Delmar Signal Interconnection

Delmar Boulevard serves as an important transportation corridor in northern Saint Louis, Missouri. As a minor arterial road, it accommodates multiple modes of transportation which connects residents to essential goods, services, and destinations. This corridor links 3 wards and 8 neighborhoods, schools, firehouses, and hospitals. The upgrade of this vital multimodal transport route will directly benefit the community by increasing mobility, safety, and access to pedestrians, cyclists, motorists, and transit users.

Project Location / Description

The 2.7 miles of the project corridor are on Delmar Boulevard from DeBaliviere Avenue on the west to Vandeventer on the east. There is a significant need to maintain and improve traffic management and safety within the City’s complex transportation network, including the reduction of motorists travel times and vehicle emissions. This project enhances the Intelligent Transportation System (ITS) infrastructure to better facilitate traffic incident and congestion management actions undertaken by the Real-Time Transportation Intelligence Center (TIC).
