Installation of five access systems to trunnion bearings and one ladder to reach the river channel below the Dam will allow for routine inspections and maintenance to occur without increased risk to personnel.

Elevations are as follows:

-Service Bridge Deck Elevation=170.00ft.

-Pier/Abutment Concrete Elevation= 145.00ft -River Channel Bottom=130.00ft.

Note: contractor is responsible for final measurements.
