Facility Overview

The Metropolis parking facility at 255 Grand Union Boulevard is an ultra-modern, covered multi-story parking garage situated directly in the heart of Somerville’s vibrant Assembly Row neighborhood. Equipped with state-of-the-art Metropolis computer-vision and automated license plate recognition (ALPR) technology, the facility offers a seamless, ticketless drive-in and drive-out parking experience. The interior features wide, clearly demarcated stalls, one-way driving lanes, and clean, bright LED illumination. The garage comfortably accommodates standard passenger cars, crossovers, and full-size SUVs, though oversized commercial cargo vans and lifted trucks should be mindful of the standard garage clearance height of approximately 6 feet 10 inches (2.08 meters).

Visitor & Driver Tips

First-time visitors using Metropolis can sign up in advance with their license plate and payment method for seamless automated billing upon exit, though you can also easily scan on-site QR codes displayed near garage entrances and elevators. Weekends and Friday evenings experience strong peak traffic due to dinner and cinema rushes; arriving slightly before peak dining hours guarantees lower-level spaces. If your destination is the riverfront or MBTA station, parking near the western elevator banks provides the quickest pedestrian exit routes.
