Traffic problems on Strobel Road, Spring Hill Road and along Route 111 could be easing relatively soon, according to a review of some of the infrastructure improvements around town. With Trumbull High closed from March to September, work on Strobel Road proceeded almost without interruption, Mascia said. As a result, the project is “on track and way ahead of schedule,” he said. In the private sector, there is more than $170 million in construction underway in town, according to Economic and Community Development Director Rina Bakalar. Bakalar said the new developments had also helped business development in town. Dan Onofrio, president of the Bridgeport Regional Business Council, which includes the Trumbull Chamber of Commerce, agreed.
