A truck crash on the Maine Turnpike in Ogunquit is causing significant traffic delays late Tuesday afternoon for travelers heading in both directions. The Maine Turnpike Authority said the truck rolled over about 3:45 p.m. at mile 14 northbound. Left travel lanes on both sides of the highway were closed to traffic because the box truck landed on top of the median guardrail. Erin Courtney, spokeswoman for the Maine Turnpike Authority, said that no one was injured in the crash, which involved only the truck. A second northbound lane – there are three travel lanes on that side – may have to be closed Tuesday evening in order to remove the truck.
