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 Mid-October, SR 25, between Eckel Junction Road and Jefferson Street, will be reduced to one lane in each direction.
Through September, 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.
Through Friday, September 8, the ramp from southbound I-475 to SR 25 will be closed for about 5 weeks.
Effective Friday, September 8 at 9pm, through Monday, September 11 at 6am, SR 25 over I-475 will be closed for one weekend. All ramps will remain open. Northbound detour: southbound I-475; norhtbound I-75; US 20 (Exit 193); southbound I-75; northbound I-475; SR 25 (Exit 2). Southbound detour: northbound I-475; US 24 (Exit 4B); southbound I-475; SR 25 (Exit 2).
Effective Monday, September 11 at 6am, the diverging diamond interchange traffic pattern will be in effect.
*MOTORISTS ARE ADVISED OF CHANGING TRAFFIC PATTERNS.*
Effective Monday, September 11 at 6am, the ramp from northbound I-475 to SR 25 will be closed for about 4 weeks.
Roadwork is expected to be complete in mid-October.
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.
