This project is part of ODOT's continuous efforts to preserve and maintain the state's structures and bridges. Seismic retrofitting work on the Boones Bridge involves connecting the bridge beams to supports and columns.
Work also includes installation of energy dissipating bearings.
Nearly all the work is conducted under the bridge and presents little, if any, restriction of vehicular traffic. Expansion joint replacement will enhance the bridge's flexibility under traffic movement and temperature changes. Bridge surface activities will affect Wilsonville, Charbonneau and general I-5 motorists beginning in March 1999. Motorists can expect inconveniences on I-5 and the connecting ramps during the spring and summer of 1999. These dollars are being redirected to provide additional pavement preservation projects statewide.
