In 2007, E.T.& L. completed its largest project to date: a $37 million grade-separated interchange replacing the Sagamore Bridge Rotary, infamous for causing terrible traffic on and off the popular vacation destination of Cape Cod. The project essentially lowered Route 6 (Scenic Highway) below Route 3 and constructed a new Route 3 bridge, thus streamlining travel to the Cape.

In order to allow traffic to flow during construction, three (3) temporary bridges were erected to carry travelers from Church Lane, Route 3 northbound and Route 3 southbound over what would become Route 6. Now completed, a new four lane bridge carries Route 3 over Route 6 and directly onto the Sagamore Bridge.
