Permit Description: ADOT On-Call Statewide Bridge Engineering, Contract No. 2019-10.01 - Bridge Inspection Task Order 12 The work for this project consists of an In-depth Bridge Inspection for one Arizona Department of Transportation Structure located on 22nd Street in Tucson Arizona. The structure is 22nd Street SPRR OP (ADOT Structure #09011). The structure carries Eastbound and Westbound 22nd Street over the Union Pacific Railroad tracks and railyard property, as well as Campbell Avenue, and Aviation Parkway (State Route 210). The bridge will be accessed from the ground using a bucket truck and boom-lift from both inside and outside the railroad right-of-way. Please note that due to posted weight restrictions on the bridge, the bridge cannot be accessed with an under-bridge inspection vehicle (snooper truck). The top side of the bridge will be accessed from 22nd Street using traffic control with lane closures in each travel direction. The underside of the bridge outside of railroad right-of-way will be accessed using a bucket truck and boom-lift using phased lane closures on Campbell Avenue anticipated during daytime hours, and Eastbound and Westbound Aviation Parkway (State Route 210) anticipated during nighttime hours. The underside of the bridge within the railroad right-of-way will be accessed using a boom-lift and railroad flagging. The inspection within the railroad right-of-way is anticipated to take place during daytime hours. The inspection is tentatively scheduled to occur in mid-to-late October of 2023.
