The bridge will be shut down from 9 a.m. Tuesday through 9 a.m. Thursday. Some lanes have been closed on the bridge during non-peak hours since April when upgrades to the structure began. Construction is expected to run until at least mid-November, state Department of Transportation officials said in April. The department had said then that the bridge would need to fully close for major mechanical upgrades, which would be done during the nighttime for a few weeks sometime after Oct. 1.
