Crews are installing a Diverging Diamond Interchange (DDI) at I-475 and SR 25 in Perrysburg, providing pedestrian access across interchange, and providing highway lighting in the corridor. E.S. Wagner Co., of Oregon, Ohio, was selected as the prime contractor for this $8 million project.
Through September, SR 25, between Eckel Junction Road and Jefferson Street, will be reduced to one lane in each direction.
Effective Thursday, June 22 at 9pm, the left turns from southbound SR 25 to southbound I-475 will not be permitted. Traffic will be detoured to Jefferson Street to make a U-turn. But a left turn lane for northbound SR 25 to northbound I-475 will be maintained.
In mid-July, the ramp from southbound I-475 to SR 25 will be closed for about 5 weeks.
Immediately following that closure, SR 25 over I-475 will be closed for one weekend 9pm Friday to 6am Monday.
Following the weekend closure of SR 25, the ramp from northbound I-475 to SR 25 will be closed for about 4 weeks.
When that ramp opens, the Diverging Diamond Interchange will be in its functional traffic pattern.
Roadwork is expected to be complete in late September.
Studies have shown that a DDI reduces crashes between 19% and 46%. There are 26 conflict points in a conventional interchange compared to only 14 in a DDI. Other benefits from a DDI include a reduction in signal delays and shorter pedestrian crossings. There is also a DDI on Roberts Road over Interstate 270 in Columbus.
