About this Location

Facility Overview

The Colonial Parking garage at 1140 Connecticut Ave NW offers premier, sheltered underground parking right in the bustling heart of Washington, DC\'s Golden Triangle and Central Business District. Positioned along one of the capital\'s most prestigious commercial avenues between M Street NW and Desales Street NW, this subterranean parking deck serves tenant professionals, legal associates, diplomatic visitors, and day visitors alike. The facility features standard marked stalls, smooth one-way drive aisles, and elevator/stairwell access linking directly to the street and lobby. Vehicle clearance is restricted by subterranean deck limits (typically 6 feet 2 inches), making the garage optimal for compact cars, sedans, mid-size crossovers, and standard SUVs, while high-roof cargo vans, dual-rear-wheel trucks, and lifted 4x4s should seek open-air alternatives nearby.

Visitor & Driver Tips

Due to the building\'s business-district location, inbound traffic peaks heavily between 8:00 AM and 9:30 AM, with evening rush hours starting around 4:30 PM. Reserving your daily spot via parking apps such as ParkMobile or SpotHero prior to arrival can ensure parking availability and lock in competitive early-bird tariffs. Take note of your assigned level and space number before taking the elevator up, and double-check your vehicle antenna height against overhead entrance warning bars to prevent damage.
