This proposed project addresses the existing poor pavement condition, late stages of deterioration, and the roadway’s substandard lighting. The project also proposes widening shoulders, reconstruct driveway approaches, and updating the Intelligent Transportation System (ITS) elements. This project is fully funded and programmed in the 2018 SHOPP for approximately $25.2 million, construction is estimated to begin in 2020. The scope, as described for the preferred alternative, is consistent with the project scope programmed by the Commission in the 2018 SHOPP.
