KENT COUNTY, MI – The Michigan Department of Transportation plans to move a 2,100-ton bridge into its permanent position starting this tonight.
The project is using bridge slide technology. The new bridge was constructed adjacent to the old bridge. The new bridge is being slide into place this weekend.
Bridge slide technology greatly reduces the amount of time a bridge is out of service.
MDOT is replacing and widening the M-50 (Alden Nash Avenue) bridge over I-96 in Lowell Township. The new structure will be wider by 33 feet for a total of 68 feet, accommodating four 12-foot lanes (two through-lanes and two left-turn lanes) and two 10-foot shoulders. A right-turn lane will be added for southbound M-50 traffic to westbound I-96.
The eastbound I-96 off ramp is also being widened to two lanes, accommodating both left and right turns. The westbound I-96 off ramp will be widened to better accommodate left and right turns.

M-50 Alden Nash Avenue closes over I-96 and remains closed until no later than Monday, October 20, 5 a.m. DETOUR: From westbound I-96 to access M-50 south of the expressway, exit at Nash Highway, north to Grand River Avenue, west to Segwun Avenue, south to 52nd Street, west to M-50. From eastbound I-96 to access M-50 north of the freeway, turn south on M-50, east on 52nd street, north on Segwun Avenue, west on Cascade Road to M-50.

I-96 eastbound and westbound closes at exit 52 M-50 Alden Nash Avenue. Eastbound I-96 will retain two lanes of traffic on the exit and entrance ramps to get past the closure. Westbound I-96 will be reduced to one lane to get access to the exit and entrance ramps. MDOT plans to have I-96 reopened by 10 a.m. Saturday, October 18, but hopes the bridge slide process will be completed earlier. Right turns onto M-50 will be allowed. Opening I-96 is a high priority.
