I-385 Widening and Improvement Project, Greenville, SC

The I-385 Widening Project is located east of the city of Greenville, SC and includes widening 5.8 miles of the existing
route from I-85 to just west of the US Route 276 interchange and the replacement of several bridges and interchanges.
The existing I-385 roadway section is being widened from 2 lanes to 4 lanes in some areas and 4 lanes to 6 lanes in
other areas. Specific bridges to be replaced as part of this project include the Hillside Road and Lowndes Hill Road
overpasses as well as the SC 276, SC 291 and S-273 bridges. The proposed widening effort will help to provide the
necessary future capacity for the I-385 route, enable the route to be operated more safely and efficiently, and reduce
delays and accidents.
