New South Roundabout Opens at New Florence Interchange

HANNIBAL –The bridge replacement and interchange project located on Missouri Route 19 and Interstate 70 is set to enter the final stages including reduced traffic impacts.

Weather permitting, September 1, the following portions of the project will be complete and open to traffic:

  • New I-70 eastbound off and on-ramps
  • The South Outer Road (Tree Farm Road) east and west of MO 19
  • The south roundabout

Construction continues on the eastern portion of the north roundabout and islands on the south roundabout.  During this time, drivers can expect to experience the following traffic impacts:

  • The North Outer Road, Booneslick, west of MO 19, will open from Highway 19 to FastLane, but will have right-in/right-out only access at Highway 19.  Drivers wishing to travel northbound on MO 19 from the North Outer Road/Booneslick will continue to use Clark Drive.
  • Upon exiting WB I-70, traffic will detour onto the temporary off-ramp and onto a portion of the North Outer Road/Booneslick.  This detour will accommodate one-way traffic only and access to businesses will be right-in/right-out only.  At the intersection with MO 19 only right turn movements will be permitted to travel north.  Motorists wishing to travel southbound on MO 19 from the WB I-70 exit ramp will utilize the Clark Drive extension as a detour loop in conjunction with the north outer road.
  • The North Outer Road/Booneslick will be closed to eastbound traffic between MO 19 and Coop Road. 
  • The I-70 WB on-ramp will re-open from southbound MO 19.  Northbound MO 19 traffic will access this ramp by taking Clark Drive to the North Outer Road.
  • Over the next several weeks, temporary nighttime lane restrictions will be in place between the hours of 7 p.m. and 6 a.m. to allow for placement of concrete for the islands at the south roundabout.

Drivers can learn more about the specific construction phases of the project and traffic impacts by viewing the video series created to help keep drivers informed.  This project is currently progressing ahead of schedule and current work is outlined in the stage 4 and stage 5 construction videos found online at: Missouri Route 19 Bridge Replacement and Interchange Improvement over I-70 | Missouri Department of Transportation (modot.org)

We ask that motorists please be attentive in work zones for their safety and the safety of highway workers.  All work is weather dependent, and signs and message boards will be in place to alert motorists, as schedule changes occur.
