I-20 Widening Project

The South Carolina Department of Transportation welcomes you to the official Website for the I-20 Widening Project.

SCDOT proposes to widen Interstate 20 between I-77 to just east of Spears Creek Church Road (Exit 82) in northeast Richland County. This is one of the busiest sections of I-20 in the county.

Project Information

  • The project includes widening to six lanes and mainline corridor rehabilitation of 6.7 miles of I-20.
  • The majority of the widening will occur in the median utilizing concrete pavement.
  • The completed project will include paved shoulders and three 12-foot travel lanes in both directions.
  • Two travel lanes in each direction will be open to traffic during construction, except for limited nighttime lane closures.

Project Schedule

The project began construction on October 1, 2012 and is estimated to be completed in less than 24 months. Measures will continue to be taken to expedite the construction process.
