Officials with the Delaware Department of Transportation said the SR 1, Thompsonville Grade Separated Intersection and ramps are open to traffic.
This $11.5 million project included the creation of an overpass with on and off ramps for north and southbound traffic connecting with Route 1 from Thompsonville Road.
The project also extended Thompsonville Road to the intersection of Tub Mill Road and Church Hill Road. The improvements allowed the removal of the existing traffic signal at the Thompsonville intersection and the removal of median crossovers in the immediate vicinity.
The contractor for these improvements is Mumford & Miller Concrete Inc. in Middletown.
“The completion of the Thompsonville interchange is another major milestone in a series of improvements we have been making on Delaware’s Route 1, and it reflects the progress that is possible for improving the safety and efficiency of our transportation system as a result of recent investments in our Transportation Trust Fund,” Gov. Jack Markell said. “This interchange will significantly reduce traffic congestion from Dover to the beach resorts area, while making the road safer for residents and visitors, complementing similar projects at interchanges further north and south.”
“The completion of the Thompsonville grade-separated interchange means that traffic on Route 1 will now flow more freely and safely,” said DelDOT Secretary Jennifer Cohan. “More than 120 crashes occurred within a 10th of a mile of the traffic signal at Thompsonville Road during the 10 years prior to the start of this project. By eliminating the signal and replacing it with a grade-separated interchange, we eliminate the need for Route 1 traffic to stop and eliminate the cause of far too many rear-end collisions. We expect similar safety improvements elsewhere along the Route 1 corridor as we continue work on other grade-separated interchanges.”
The SR 1 and Thompsonville Road Project, is part of DelDOT’s long-term plan to improve safety and ease traffic congestion along the entire SR 1 corridor from Dover to Lewes.
Similar ongoing projects include improvements at SR 1 and south Frederica and at SR 1 and Little Heaven. The work at south Frederica is due for completion in the spring of 2018. The work at Little Heaven is due for completion in the fall of 2018.
The next related project to begin construction will be an interchange at SR 1 and Northeast Front Street, planned to start construction in the fall of 2017. In addition, a connector road will be constructed between Northeast 10th Street and Northeast Front Street to eliminate the grade crossover.
A community workshop to discuss preliminary plans for building an interchange at SR 1 and SR 16 will be held from 4 p.m. until 7 p.m., on Wednesday, November 16 at Eagles Nest Christian Academy, 26633 Zion Church Road in Milton. That project is tentatively planned to begin construction in the spring of 2020.
