Three west-bound lanes on H-1 Freeway Airport Viaduct will be closed Sunday for pavement repair work.

The closure of the three leftmost lanes will run from 6 a.m. to 10 p.m.

All on- and off-ramps will remain open during the work.

The roadwork is part of a $9.1 million project to repair potholes along a three-mile stretch of the Airport Viaduct between Middle and Valkenburgh streets.

Crews are using fast-forming concrete to fill potholes. To minimize vibrations while the concrete cures, the speed limit in the work area will be 15 mph.

Westbound drivers are advised to use caution in the area and allow for extra travel time.
