The Whirlpool Bridge reopens Monday, and the Nexus Enrollment Center along with it.
The bridge closed on April 1 to allow crews to work on the Niagara Scenic Parkway.
Two miles of roadway were removed, including a viaduct that crossed directly over the bridge.
Now that the viaduct work is complete, the bridge is safe to reopen for traffic.
Nexus lanes are open again as well, giving pre-screened travelers to cross into Canada more quickly.
The bridge is open from 7 a.m. until 11 p.m. daily.
Nexus services, including enrollment, are available from 8 a.m. until 8 p.m. daily.
