State Route 210 (SR 210), also known as the Barraza-Aviation Parkway, is a state highway located in Tucson, Arizona alongside the Union Pacific railroad. Most of it was opened around 1998.
Between its western terminus at Broadway Boulevard and Kino Parkway, SR 210 is a controlled-access expressway; further east, it is a limited-access highway with at-grade intersections and traffic lights until its eastern terminus at Golf Links Road (at the western edge of Davis-Monthan Air Force Base).
SR 210 currently does not intersect any other state or national routes, but is planned to intersect Interstate 10 in the future.
The initial section of SR 210 has a very long history in Tucson. Called the Barraza-Aviation Highway, all but the last few miles were completed in the 1990s. On July 8, 2008, the Mayor and Council voted 6–0 to approve Alignment 3.d., which would extend SR 210 to I-10 at the current St. Mary's Road overpass.
According to historian David Leighton of the Arizona Daily Star newspaper, the name "Barraza" is named for union leader Maclovio R. Barraza and the word "Aviation" derives from the Aviation Field, now called Davis-Monthan Air Force Base.
After the passage of the Regional Transportation Authority plan, a portion of the sales tax increase will pay for an extension of the parkway from Broadway Blvd. to 6th Street. The plan is called Downtown Links. The road will go alongside the Union Pacific Railroad. Also, the railroad crossing on 6th St., west of Stone Avenue, will be improved, providing a new underpass below the railroad. This will allow free-flowing traffic between I-10 and the new parkway.
The parkway will be four lanes wide. Construction in the second phase of the RTA plan had been scheduled to start in 2011.
ADOT is undergoing a study to connect SR 210 to I-10 at Valencia Road or Wilmot Road in southeast Tucson. The new roadway would be built to freeway standards from I-10 to the current terminus at Golf Links Road.
