Some inspections may significantly interfere with normal traffic movement and could endanger the bridge inspectors and traveling public. Coordinate these inspections with District personnel to ensure that appropriate traffic control measures are taken.
The underside of some bridges cannot be reached for inspection by conventional ladders. Perform these inspections using a vehicle with under-bridge platforms. TxDOT owns and operates several of these vehicles. Small boats are also available.
Coordinate in advance with the Inspection Branch of the Bridge Division to use any Division specialized access equipment.
