Traffic Returned to Two Lanes in Each Direction Wednesday Morning

The project to rehabilitate the bridges that carry Interstate 70 over the Lamine River west of Boonville is complete two weeks ahead of schedule. Traffic returned to two lanes in each direction Wednesday morning.

Use the Zipper Merge to Cut Congestion in Half!

MoDOT is urging motorists to use the zipper merge concept when traveling through this 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:

  • Reduces differences in speeds between two lanes;
  • Reduces traffic backups by 40-50 percent.
  • Creates a sense of fairness and equity that all lanes are moving at the same rate.

traveler mapSmart Work Zone and Other Travel Tools

  • The message boards along I-70 will alert motorists to the bridge work.
  • In addition, a Smart Work Zone system is in place to keep motorists informed and traffic moving. The system uses cameras and sensors to determine travel times through the project limits and provide real-time travel updates to motorists via message boards.
  • Other tools that provide traffic information to motorists, include:
    • Traveler Information Map - located at www.modot.org, the map provides a variety of tools to help drivers see current traffic conditions on I-70, including incidents, real-time traffic flow and traffic cameras.
    • Incidents - Vehicle crashes and other incidents are noted on the map,which will inform drivers that the road is closed, to expect delays or that delays are possible.
    • Real-time traffic flow - The map also shows real-time traffic flow, with green showing traffic is moving normally, yellow indicating that traffic is moving at a medium rate and red meaning traffic is moving slowly.
    • Traffic cameras - There are traffic cameras spanning the I-70 corridor between St. Louis and Kansas City.
  • 24-hour toll-free number – MoDOT’s toll-free number – 888-275-6636 – is answered 24 hours a day, seven days a week and 365 days a year. Callers can speak with a customer service representative to get the latest traffic information.
