Hilliard officials say the city has experienced no significant traffic problems in the first few days following the 90-day closure of the Roberts Road bridge.
"We haven't received any complaints," said traffic engineer Letty Schamp.
The Ohio Department of Transportation is in the midst of a $9.7-million project to construct a state-of-the-art "diverging diamond interchange" at Roberts Road in Columbus.
The interchange frequently is used by motorists to access residences and businesses in the southern areas of Hilliard and on the Hilliard-Rome Road corridor.
The posted detour for motorists traveling north on I-270 is to continue to Cemetery Road and use the ramps to access southbound I-270.
From the southbound lanes of I-270, vehicles can exit to travel west on Roberts Road toward Hilliard.
"The (posted) detour includes using only the ramps, so it isn't putting more cars on Cemetery Road," Schamp said.
Schamp said Hilliard Mayor Don Schonhardt travels Cemetery Road daily and has reported no significant problems with traffic.
"People also tend to find their own way (around road closures), so it typically evens out," she said.
The Roberts Road bridge closed July 29 and is scheduled to remain closed for 90 days, said Nancy Burton, a spokeswoman for the Ohio Department of Transportation.
Burton said the diverging diamond interchange would be the first of its kind in Ohio.
"It allows for more capacity," she said, adding that it will result in fewer backups on the ramps.
Burton said it also will increase safety because an average of 100 accidents occur at the Roberts Road interchange each year.
In a diverging diamond interchange, northbound traffic on I-270 will have longer, separate lanes to go either east or west on Roberts Road, regulated by a traffic signal.
Southbound traffic on I-270 will be managed in the same manner.
Eastbound and westbound on traffic on Roberts Road will be able to enter the freeway more efficiently, as well, Burton said.
The project is scheduled for completion by the end of the year, Burton said.
