The Pearl Harbor Memorial Bridge, known locally as the Q-Bridge because it spans the Quinnipiac River, is central to the I-95 New Haven Harbor Crossing Corridor in Connecticut. The 7.5-mile stretch of highway was originally designed and constructed in the late 1950s to carry 40,000 vehicles daily.
The region has grown, and the corridor is straining under the weight of more than 140,000 vehicles per day. PCL was hired by the Connecticut Department of Transportation to ensure the new 10-lane twin Pearl Harbor Memorial Bridge will provide relief to commuters and commercial traffic.
AHEAD OF THE CURVE
The bridge will be what is called an extra-dosed cable-stayed bridge, and will be the first of its kind in the United States. Extra-dosed bridges have structural characteristics similar to traditional bridges, and they have been successfully used in both Europe and Japan.
The Q-Bridge will also provide a distinct aesthetic structure for the City of New Haven and the South Central region of Connecticut and will advance the nation's bridge technology by using this new and innovative type of design.
BUILT TO SUIT
PCL, with its joint-venture partner, Walsh Construction, is building the bridge to meet the needs of drivers, as well as the specific needs of the local area. The Q-Bridge design allows for shorter main towers that meet air traffic restrictions from nearby New Haven Airport.
The unique design also provides a longer main span whose wider navigation channel will benefit boat and barge navigation under the bridge. This wider channel requires fewer supports in the water, which means less disruption to the marine environment.
