Proposed Traffic Flow
The Sunset Split will separate eastbound and westbound traffic on US 378 into two, one-way roadways. This will involve the construction of a new location roadway north of existing US 378 and reconstruction of existing Dedrick Drive, extending from Corley Mill Road westward to a tie in point beyond Northside Boulevard at Darby Ambrose Road. The new roadway will carry westbound US 378 traffic, while the existing US 378 roadway serves eastbound traffic. The images and videos below will take you through the new traffic flow patterns.
