A bridge replacement on I-45 will have to wait one more week.

Officials with the Texas Department of Transportation delayed the start of demolition on a northbound and southbound bridge over Park Road 40 in Huntsville. TxDOT sighted weather as the delay for the project, which is now expected to begin next weekend.

During the beginning of the project TxDOT will close a portion of Park Road 40 in between the on and exit ramps. This closure on PR-40 will be from 5 a.m. on Friday, Sept. 14 to 5 a.m. on Monday, Sept. 17.

“This closure is necessary to remove portions of the existing northbound and southbound I-45 bridges over PR 40,” TxDOT said in a release. “The construction of the median portion of the new I-45 overpass will begin after removal of the existing median section. Traffic will remain in its present configuration on I-45 until the new concrete pavement and bridge in the median are completed.”

Temporary detour routes will be signed, and portable message boards will be placed in affected areas at least one week prior to the closure.

The bridge replacement is part of the six-mile widening project from the Walker/ Montgomery County line to Huntsville. This project will widen IH-45 to six lanes and will replace the State Park Road 40 bridges and southbound SH 19 Flyover.

“During the 3-year project, multiple lane shifts and relocation of traffic will take place at various times to accommodate construction activity,” the release added. “IH-45 and the southbound lane of State Highway 19 will also be closed at various times for safety of the traveling public and construction workers.”

The reconstruction of IH-45 will take place in two major phases. Phase 1 is under way and will include the addition of Veteran’s Memorial Bridge, northbound State Highway 19 bridge and a new southbound State Highway 19 flyover. Phase 2, will include replacement of the Park Road 40 bridges.

The construction is under Johnson Bros. Corporation, a Southland Company, which was awarded the construction contract at $116 million.
