Two NH Transportation Projects Win National Awards
Memorial Bridge and Hooksett Open Road Tolling Recognized for Engineering Excellence

Two New Hampshire transportation improvement projects completed within the past year have been recognized with national awards for engineering excellence.

The Hooksett Open Road Tolling (ORT) Plaza Conversion Project" and the "Portsmouth Memorial Bridge Replacement" each received a 2014 "National Recognition Award" from the American Council of Engineering Companies (ACEC). The awards "demonstrate exceptional achievement in engineering."

Both the Hooksett ORT project and the Memorial Bridge project presented engineering challenges, and both were constructed and completed on very aggressive schedules. The Hooksett ORT lanes on Interstate 93 (Everett Turnpike) opened weeks ahead of schedule on May 29, 2013. The new Memorial Bridge connecting Portsmouth, New Hampshire and Kittery, Maine via US Route 1 was completed in just over a year and a half and opened to traffic on August 8, 2013.

The Hooksett ORT project involved the demolition of six conventional toll lanes and the construction of four lanes (4,500 feet) of highway speed toll lanes, the widening of 9,000 feet of approach roadways, and the realignment of four interchange ramps. The conversion to ORT allowed the New Hampshire Department of Transportation (NHDOT) to cost effectively increase traffic capacity and safety at the toll plaza while providing environmental benefits. Since its opening, E-ZPass use at the Hooksett Toll Plaza has increased 4.6%, up to 66% of all vehicles.

The Memorial Bridge project replaced a closed steel bridge with a new modern lift bridge that honors its predecessor in design while featuring some of the latest engineering innovations. It is the first bridge in the United States to eliminate the use of gusset plates, and includes the use of modern techniques for cold bent steel fabrication. The steel bridge has a metalized coating with a service life of up to 50 years.
