Didn't look like a back-up today when I was on Rt. 128. A long but easy detour would be to exit at Blue Rock Road and head west about 5 miles. At the stop sign just past Great Miami River turn left. Continue west (New Haven Road) until about 2/3 mile after the flashing red light/stop sign to Dry Fork Road which Y's to the left. Go past I-74 to the stop sign and turn right (Simonson Road). This dead-ends into Kilby Road, turn left. About 5 miles to I-275.
