PSI wins an ACEC National Award for 11th Street N.W. Bus Priority Improvement project in Washington, D.C.
Bus transit is a critical lifeline for many of Washington, DC’s residents, particularly vulnerable and historically underserved communities who rely on it for access to jobs, healthcare, and essential services. Precision Systems, Inc. (PSI) led the District Department of Transportation’s (DDOT) 11th Street NW Bus Priority Improvement Project – extending from Pennsylvania Avenue to Massachusetts Avenue NW – significantly improving transportation efficiency and safety along this vital corridor.
PSI’s strategic design introduced dedicated bus lanes, upgraded facilities for cyclists and pedestrians, and enhanced overall traffic operations.
Historically, the 11th Street NW corridor, connecting Downtown and Penn Quarter, faced severe congestion and safety challenges – disproportionately impacting bus riders and non-motorized users, many from lower-income households. Over 9,000 vehicles traveled this small arterial daily, leading to chronic delays, unreliable bus service, and hazardous conditions for pedestrians, cyclists, and scooter users.
Through innovative engineering, PSI transformed the corridor’s functionality:
- Dedicated Bus Lanes: Eliminated obstacles for buses, significantly increasing trip speed and schedule reliability.
- Modular Bus Platforms: Installed four 100% recycled modular boarding platforms – cost-effective, ADA-compliant, and strategically placed based on ridership patterns.
- Concrete Bus Bulb-Outs: Constructed curb extensions with trench drains to enhance boarding efficiency and meet accessibility standards.
- Signal Improvements: Modified traffic signals to extend leading pedestrian intervals, implement transit signal priority, and separate vehicle turning movements – enhancing safety and flow for all users.
This integrated design not only improved mobility but delivered meaningful equity outcomes, making reliable, safe transit access a reality for thousands across the District.
