Planning a move while dealing with Cambridge Street Bridge construction sounds like a logistical nightmare, doesn't it?
The bridge replacement project has limited westbound traffic to a single lane. This disruption will continue through October 2026. Hundreds of bicycle users and pedestrians were funneled to share a narrow, broken sidewalk in the construction zone for most of last week.
You need to understand your route options whether you're moving in Allston, commuting through Brighton, or trying to avoid Allston detours around the I-90 bridge closure.
We've created this complete guide to help you traverse the cambridge construction smartly. You'll find the best detour routes, timing strategies and practical tips for a smooth move during the cambridge street project.
Understanding the Cambridge Street Bridge Construction Project
MassDOT added the Cambridge Street Bridge replacement to the Allston Multimodal Project scope in Spring 2024. This rehabilitation work affects one of the busiest corridors in the area. Cambridge Street carries 38,000 vehicles daily.
The contractor performs multiple construction activities on Cambridge Street over I-90. These include concrete substructure repairs, cleaning and priming the steel bridge structure, and installation of bridge shielding and brackets. The work also involves removal of existing fencing and railings. So expect lane closures during daytime hours from Monday through Friday, 6:00 a.m. to 6:00 p.m. Nighttime closures run from Monday through Saturday, 9:00 p.m. to 6:00 a.m..
Brighton Avenue or Western Avenue provide reliable detour options to bypass truck delays around the construction zone when you move. Mid-week moves help you avoid peak construction congestion when crews intensify their work schedule.
The project's work zone continues to occupy sidewalks and bike lanes on the bridge's northern side. Westbound car traffic remains restricted to a single lane through the construction period, adding to these space constraints.

Best Detour Routes for Moving in Allston and Brighton
Brighton Avenue serves as your main alternative at the time Cambridge Street Bridge construction blocks your preferred path. This corridor handles more than 14,000 MBTA bus passengers each day between Union Square and Packards Corner, along with 1,300 bike riders. The eastbound bus-bike lane opened in summer 2019. The westbound lane followed that fall.
Western Avenue offers another option you can rely on. This major one-way arterial connects Cambridge's Central Square to Allston and Brighton. The route accommodates trucks and busses, which makes it suitable for moving vehicles that work around the I-90 bridge closure.
The Franklin Street footbridge remains available for bike and pedestrian detours despite construction barriers. Traffic counts in June 2025 recorded 613 and 570 bike riders on consecutive weekdays near the northern footbridge entrance at Alcott Street. These numbers represented over a quarter of the street's total vehicular traffic.
GPS apps give you up-to-the-minute construction updates. Open your Waze settings and enable options to avoid toll roads, ferries, or freeways based on your priorities. Google Maps displays traffic layers with official data from transportation agencies. This helps you identify closures before departure.

Planning Your Move Around Cambridge Street Construction
A Boston moving permit guarantees you legal parking space during the Cambridge Street Bridge construction disruptions. A standard one-day permit costs $69 and reserves two non-metered spaces from 7 a.m. to 5 p.m.. You must pay an additional $40 per day per meter if your reserved area has metered parking. Apply online at least 15 days before your move, or submit in-person applications at least three days ahead.
Post your 'No Parking' signs at least 48 hours before the permit start time for non-metered spaces. For metered locations, you only need to post signs one day before your move.
Traffic builds around 7:00 a.m. and lasts until 9:30 a.m., while evening rush begins around 4:00 p.m. and continues until about 7:00 p.m.. You save hours on the road when you plan your move outside these windows. Mid-week moves between Monday and Thursday prove 30% faster than weekend moves.
Avoid the August 31 to September 2 window when the city blocks popular moving locations for mass student move-ins. The Cambridge Street Bridge work eliminated over 30 parking spaces near Harvard Avenue where moving trucks parked before. Check the Allstonia construction update portal before selecting your date.
