News Center Maine reports, the Maine Turnpike, the nation’s “second super highway,” is marking its seventy-fifth anniversary today. The 109-mile-long tollway running from Kittery to Augusta “is one of the state’s busiest stretches of road, carrying 10 percent of the state’s traffic and about 55 percent of the state’s freight.” The article looks at the highway’s construction and the legislature’s decision in the 1970s to keep the facility tolled and under management of an independent authority. Turnpike spokesperson Erin Courtney says customers are being invited to stop at the authority’s headquarters in Portland to pick up a commemorative gift.
