Temporary overnight ramp closures on Interstate 40 are scheduled to test wrong-way detection systems. These closures will occur intermittently from 10 p.m. to 6 a.m. on Tuesday, July 8, Wednesday, July 9, and Thursday, July 10.
Crews will close specific off-ramps in two-hour intervals to conduct the tests. The wrong-way detection systems being tested include vehicle sensors, closed-circuit television cameras, illuminators, hardware controllers, warning devices, and communications equipment. If a motorist is detected traveling in the wrong direction, LED lights will flash as a warning. An alarm will also be sent to the Arkansas Department of Transportation Traffic Management Center for tracking purposes.
The plan is to close only one ramp at a time and complete testing on three to four ramps each night. Emergency responders will have access to the ramps at all times; other motorists must use alternate exits.
The affected ramps include:
– Eastbound Exit 148
– Westbound Exit 148
– Westbound Exit 193
– Eastbound Exit 199 (White River Rest Area)
– Westbound Exit 199 (White River Rest Area)
– Eastbound Exit 202
– Westbound Exit 202
Traffic control measures will be implemented by Highway Police using barrels, message boards, and signage. For more travel information, visit IDriveArkansas.com or ARDOT.gov.
