Original Story:
Central Arkansas motorists need to plan ahead to avoid the southbound lanes of I-430 through the Big Rock Interchange (I-430/I-630) in Little Rock TODAY. [The map of the specific area is attached below].

Arkansas Highway and Transportation Department officials say significant changes will take place starting at 9:00 a.m.

At that time, drivers should expect delays as crews work to shift the I-430 southbound lanes between Markham Street and I-630.

All southbound lanes will be affected as a combination of lane closures involving one to two lanes will be necessary for about 18 to 21 hours. At least one southbound lane and all northbound lanes will remain open at all times during this shift.

"Safety is always the number one concern for both the workers and the motorists," said Arkansas State Highway and Transportation Department (AHTD) Director Scott Bennett. "We urge motorists that use southbound I-430 near the interchange to find another route and just stay away on May 30 so workers can transition the work area quicker and safer."

The southbound lanes of I-430 between Markham Street and I-630 need to shift to accommodate the next stage of construction. This traffic pattern will remain in place approximately four to five weeks. Three southbound lanes into the interchange are currently in place and will remain after the transition, but lane widths will be reduced, and the advisory speed will be 40 mph through the area.
