Work along Union Pacific railroad crossings northwest of Tucson may have you looking for an alternate route this week.
The railroad will close down three crossings with the first beginning Tuesday night at the Ina Road crossing.
Wednesday, the crossing at Massingale Road will be shut down, followed by a Cortaro Road crossing closure on Thursday.
All closures will begin at 9 p.m. and last until 5 a.m. the next morning.
