    From Sept. 24 to Oct. 16, the Pima County Department of Transportation, the Regional Transportation Authority and their contractor, Southern Arizona Paving will close Colossal Cave Road at both the southern and northern railroad crossings. This work is part of the Colossal Cave Road: Acacia Elementary School to Old Vail Middle School improvement project.

    This closure will allow critical roadway work to be performed, including the adjustment of roadway grade to improve visibility at Success Drive and across the railroad tracks. Business access will remain open, although the southern and northern railroad crossings will remain closed to all traffic during these dates.

    The closure was perviously only expected to last until Oct. 9, but was extended to allow the Union Pacific Railroad to work on both tracks simultaneously. Extending the closure will eliminate one of three previously anticipated closures.

    Those who routinely use Colossal Cave Road for their daily commute should plan an alternative route and allow additional time for their travels. The last point of access on Colossal Cave Road from I-10 (Exit 279) northbound will be at the business center complex just south of the railroad tracks. Both Acacia Elementary School and Old Vail Middle School will have access. 

    Colossal Cave Road north of the Union Pacific Railroad (UPRR) from Interstate 10 (I-10) will be accessible by using the Houghton Road exit (Exit 275) and traveling north on Houghton Road to Mary Ann Cleveland Way and traveling east on Mary Ann Cleveland Way to Colossal Cave Road and vice-versa.

    Starting Sept. 19 for approximately nine months, the Pima County Department of Transportation, the Regional Transportation Authority and their contractor, Hunter Contracting will close Wilmot Road from just south of Old Vail Connection Road to Andrada Road.

    The project consists of paving 7.1 miles of the two lane roadway along with paved shoulders and drainage improvements.

    On Thursday, Sept. 15, the Pima County Department of Transportation, the Regional Transportation Authority, and their contractor, Borderland Construction, will begin placing 54 bridge girders on the new Sunset Road bridge. According to the construction schedule, crews will place a total of nine girders each day between Sept. 15-22. The following is a schedule of the placement and routes:

    September 15, 16, and 19: The girders will be placed along the eastern half of the new Sunset Road bridge. The 120 foot-long girders will arrive via the I-10 eastbound frontage road. 

    September 20, 21, and 22: Crews will haul the girders from I-10 to El Camino Del Cerro onto Silverbell Road to place along the western half of the new Sunset Road bridge.

    The girders will arrive at the construction site by 4 a.m. and noon each day. Pilot cars and flaggers will direct traffic during these times.

    As with all construction projects, DOT advises motorists to approach construction areas with caution and obey all traffic control devices. Motorists may expect minor delays and are encouraged to seek alternate routes. The construction schedule provided can for each of these projects can change in the event of mechanical failure or inclement weather.
