    Pavement PreservationOn Tuesday, April 19, Pima County Department of Transportation, along with its contractor, Borderland Construction, Inc., will shift southbound traffic onto the newly paved southbound lanes on Houghton Road, from 1-10 to the Pima County Fairgrounds entrance.

    Traffic attending the Pima County Fair should take the following routes for easy access:

    • Eastbound traffic off the I-10: exit on Rita Road and proceed south to Harrison Road to enter the fairgrounds from Brekke Road or Dawn Road. Entrances and parking will be available at both locations.
    • Westbound traffic off the I-10: take the Houghton Road southbound exit. Traffic should remain in the outside lane to go into the main entrance of the Pima County Fairgrounds. Brekke Road off Houghton Road will remain closed to traffic.
    • Northbound traffic on Houghton Road: will be directed left onto Dawn Road to enter the fairgrounds.


    Work will begin on the eastside of Houghton Road (northbound lanes) the first week of May.

    Please approach the area with caution and obey all traffic control devices. Traffic control changes and speed reductions will occur as work progresses. For more information on this project, visit
