Traffic patterns were due to return to normal today on the two north Grand Island bridges and the northbound exit off the I-190 for the Robert Moses Parkway.
David B. Ardman, Thruway Authority spokesman, said both north Grand Island bridges will be open until Labor Day, when northbound traffic will be diverted to the southbound bridge throughout the fall construction season. The northbound bridge will reopen for the winter, then close again next spring.
"The contractor did the pavement work this morning and a little bit of rail work," he said Wednesday. "The ramp entrance to the bridge is the last touch-up work they will have to complete."
The $19.4 million project to rehabilitate the north bridges is expected to be completed in June 1991.
Thruway authorities report that traffic delays are possible during the summer on Grand Island as work continues on the $7.8 million contract to resurface the 5-mile stretch of Niagara Thruway.
To avoid delays, Grand Island Boulevard (Route 324) can be used as an alternative route. At least one lane in each direction will be maintained at all times during construction. All entry and exit ramps will remain open.
