The City of Boulder has begun construction on intersection improvements at Table Mesa Drive and Broadway, aiming to reduce bus travel times. The project, which involves installing a dedicated southbound bus left-turn lane, affects daily operations for commuters along the heavily used Broadway corridor.
Why it matters
Operators in Boulder should anticipate ongoing traffic shifts and lane restrictions that may impact delivery logistics and employee commute times along the Broadway corridor through late 2026. This project is a key component of the city's Core Arterial Network initiative to improve transit reliability.
The project is backed by $3.98 million in funding from the Colorado Department of Transportation to support the 12,000 daily bus riders on the Broadway corridor. This intersection work is one piece of the broader Core Arterial Network initiative.
The players
City of Boulder
The local municipal government managing regional infrastructure and transportation planning.
Colorado Department of Transportation
The state agency responsible for funding and overseeing major transportation and transit infrastructure projects.
The details
Crews are modifying the intersection to allow buses to bypass traffic queues by installing a dedicated southbound left-turn lane. To maintain flow, the city is keeping at least one vehicle lane open in each direction, though operators should plan for temporary bus stop closures and lane shifts during weekday work hours.
Timeline
Construction work began at Table Mesa Drive and Broadway on October 6, 2026.
Weekday construction occurs from 7 a.m. to 5 p.m.
Market Landscape
This project is part of Boulder's Core Arterial Network initiative to prioritize transit infrastructure on key city roads. It follows similar work recently completed at Regent Drive and Broadway, signaling a consistent municipal strategy to prioritize bus-lane throughput.
Business owners should adjust delivery schedules to account for potential traffic delays near the Table Mesa and Broadway intersection through the end of 2026. Monitor the project page for specific lane closure notices that may affect customer access to storefronts along the corridor.
The takeaway
The city is prioritizing dedicated transit lanes to improve reliability for 12,000 daily Broadway riders. Operators should track the project's progress on the city website and plan for potential transit disruptions through late 2026.
