The crossovers are built north and south of the Central Avenue interchange on I-49 on the west side of Carthage and interstate traffic will be constricted to two lanes as it crosses Central Avenue and Spring River for the next few months.

The Missouri Department of Transportation said the contractor, Capital Paving & Construction LLC, Jefferson City, has completed construction of “cross-overs,” which will allow four lanes of traffic to be folded into two lanes north and south of the Central Avenue interchange.

MoDOT announced that traffic will be limited to one lane in each direction on the interstate starting on Monday, April 30, and the north side of the Central Avenue interchange will be closed.

MoDOT described these impacts over the next few weeks to traffic on I-49 around the Central interchange.

• The northbound bridge will close the week of April 30 while the driving surface is rehabilitated moving two-way traffic into southbound lanes of I-49

• Drivers should expect delays and lane closings as contractor crews close northbound bridge and shift traffic to southbound bridge, reducing traffic to one lane in each direction.

• Once the northbound bridge is completed, contractor crews will move to the southbound bridge, shifting two-way traffic into the northbound lanes

• Motorists can expect significant traffic delays and a reduced speed limit of 60 mph through the work zone

• Drivers are urged to seek alternate routes around the construction

• Some work may occur on weekends

Weather and/or unforeseen delays will alter the work schedule and the official contract completion date is Dec. 15, although highway officials say they expect the project to be completed earlier than that.

 

Bridge restoration

Matlock said the work involves replacing metal parts of the bridge around the expansion joints in the bridge's surface.

Matlock said water and salt get into these expansion joints over time and causes the metal parts to deteriorate. Those bridges were built in 1984 when the four-lane U.S. Highway 71 was built around Carthage.

The steel caps that support the bridge girders and other metal pieces in three different places on each bridge will have to be replaced.
These parts had an expected lifespan of about 30 years and are ready for replacement.

Contractor crews will also remove the bridge deck/driving surface and replace it, beginning with the northbound bridge.
