Beginning tomorrow, portions of I-20 in Jackson to be closed for repairs

I-20 in Jackson will be closed to demo and replace the bridge deck at Lynch Creek in Hinds County.

The first closure will take place on the eastbound side of I-20 and will start on Friday, October 18.

The second, on the westbound side of I-20, will begin Friday, October 25.

Each closure period will begin at 7 p.m. on Friday and end at 6 a.m. the following Thursday.

Where is Lynch Creek? As you plan your commute during the upcoming I-20 closure in Hinds County, you might be wondering where exactly the Lynch Creek Bridge is located.

The bridge goes east and westbound over the creek between Valley Street and Ellis Avenue on I-20. If you are coming from I-55, the bridge is right before Ellis Avenue. If you are coming from Clinton, the bridge is right after Ellis Avenue.

The project will have a major impact on traffic.

During construction, freight traffic will be directed to I-220 to detour around the I-20 closures. Local traffic will be directed to Highway 80. During the I-20 westbound closure, the on-ramp to I-55 north from County Line Road will close as needed to help with traffic flow on I-55 northbound.

Work will consist of removing and replacing sections of both the eastbound and westbound bridge decks. Using high pressure water, crews will remove the existing bridge deck before placing the new deck and restriping the travel lanes.  Crews will also place rip rap along the creek bed to prevent erosion.

“This is a stretch of interstate that carries approximately 93,000 vehicles a day,” said MDOT Executive Director Melinda McGrath. “Over time, the high volume of traffic has caused the bridge deck to deteriorate.”

Engineers recently found cracking and areas of exposed rebar in the bridge deck during routine inspections.  While the bridge is currently structurally sound, engineers determined repairs to each of the 51-foot by 209-foot structures were necessary.

“We understand closing an interstate in the Jackson-metro area is going to be an inconvenience for the traveling public which is why motorists should begin planning their alternate routes now,” said Commissioner Dick Hall, chair, Mississippi Transportation Commission. “In the long run, the project will extend the service life of these bridges up to 50 years.”

Motorists are reminded to be on high alert for flagmen and roadside workers. Advance warning and detour signage will be in place for communication with the traveling public.

“Bridges are a vital component to the state’s infrastructure network and this project will enhance safety and connectivity along Mississippi’s highway system,” Commissioner Hall continued. “I’d call that a good investment.”
