Recent Progress
The contractor, Max J. Kuney, is near completing the I-82 interchange bridge and the Yakima River bridge, all roadway decks are complete and traffic barrier / utility connection remain. The contractor has placed traffic in a two lane temporary configuration on the south side of the new SR 24 alignment. Yakima County 33rd Street extension is paved and open to traffic.

Design Construction Impacts
This project is projected to overrun reimburseable utililty agreements by $150,000. The contract plans did not clearly define proposed utility locations and conflicts with work after relocations.
Material delivery issues has delayed an early opening of SR 24 roadway. Final paving and safety features should be completed in the Spring of 2007.

Environmental Impacts / Compliance
This project is currently under review for a possible discharge of sediment as a result of high river flows entering the project site. The project engineer is currently working with the regulatory agencies to address the issue. The Department of Ecology reviewed the project and determined that we cannot discharge pH laden water as outlined in the permits. The project cost has increased $141,000 to dispose of this pH laden water as directed by the Department of Ecology. Temporary pollution control was under-estimated and will add approximately $600,000 to the project cost.

Impacts to Traffic
A lane will be closed on I-82 as needed for construction access. The I-82 lane closure will cause back-ups during high traffic flows. The speed limit is reduced to 35 mph on SR 24 from I-82 to Riverside Road for the life of the project. When needed, traffic on SR 24 will be controlled by flaggers. Motorists can expect delays up to five minutes and possible backups.
