JEFFERSON CITY – Work to replace the deck on the Route 63 Katy Trail bridge is progressing on schedule, and the concrete for the bridge deck is set to be poured Friday night.
The deck pour, which will start at 10 p.m., is being conducted at night when temperatures are not as high. The lower temperatures will help ensure the concrete cures properly.
“We’re at the halfway mark with this project,” said Aaron Peck, resident engineer for the Missouri Department of Transportation’s Central District. “If all goes according to plan, we should have the bridge back open to traffic by Aug. 21.”
Peck said MoDOT entered a contract agreement with Capital Paving and Construction to make sure the bridge was open before Aug. 21, the date of the total solar eclipse. Traffic on Missouri’s highways is expected to increase dramatically around the eclipse date as an estimated 1.2 million visitors come to the state to view this unique happening. Some additional work will take place after the bridge is open, and the entire project is scheduled to be completed in September.
Traffic has been traveling head-to-head on Route 63 since the southbound bridge closed on June 5 and southbound traffic was re-routed over the northbound bridge. Diverting both directions of traffic to the northbound lanes has allowed one lane of traffic in each direction to be open at all times, Peck said.
In addition to the new deck, which will widen the bridge, the project will bring the guardrail and bridge barrier on the southbound structure up to current standards. The work will allow the bridge, which is more than 60 years old, to provide an additional 20 to 30 years of service.
Message boards and signs are in place to direct traffic through the work zone. A Smart Work Zone system also is in place to keep motorists informed and traffic moving. The system uses cameras and sensors to provide real-time travel updates to motorists via message boards.
Peck also reminds drivers to use the zipper merge concept when traveling through the work zone. When traffic is slowed or stopped, the zipper merge encourages motorists to use both lanes of traffic until they reach the point where the road is closed, then take turns with other drivers to safely and smoothly ease into the remaining lane. The zipper merge could reduce traffic backups by up to 50 percent.
“So far, we’ve only experienced a few major traffic backups, mostly due to incidents that have occurred in or near the work zone,” Peck said. “We’re hoping the rest of the project runs just as smoothly.”
