RICHLAND COUNTY, SC (WIS) -

A 20-month project to widen Interstate 20 northeast of the capital city began on Monday.

The widening and resurfacing project will add one lane each way to a 6.7 mile stretch of the interstate between I-77 and Spears Creek Road (exit 82).

The $75 million project was originally slated to start in late 2010, but was delayed due to changes needed in contract documents.

The completed project will include paved shoulders, three 12-foot travel lanes in both directions, and approximately 6 miles of noise wall along various sections of the corridor.

Noise barriers will be placed along Polo Road in the vicinity of Polo Road Elementary School. In addition, barriers will be placed near Chesterbrook Academy and along the entire length of the project between Smallwood Road and Clemson Road.

According to the SCDOT, Nightly lane closures will generally begin after 7 p.m. and open prior to 7 a.m. Traffic will be shifted in various stages maintaining four lanes of traffic open throughout the construction of the interstate roadway. The speed limit will be reduced to from 60 mph to 45 mph for nightly lane closures and 55 mph for the permanent lane shifts once they are installed.

The project was awarded to Zachary Construction of Grand Prairie, Texas.

The anticipated completion date is May 24, 2014.
