M.F. Reather River Bridge Rehabilitation Project
NOE - Notice of Exemption
Caltrans is proposing to rehabilitate the MFFR Bridge and roadway, which will include the repair of a scour hole between the north bridge pier and abutment. Repair of the scour hole will include construction activities within the stream channel and will require equipment access from the north-east quadrant, which will require the existing dirt road to be graded. The scour hole will then be excavated and lined with RSP fabric with a 5.5' layer of RSP placed on top of the fabric within the excavated hole. The top of the RSP should be level with the channel bed and flush with the top of the pier footing. The RSP will begin approximately 25'. Instream construction activities are anticipated to take approximately 20 working days, which is equal to a month.
The underneath metal section of the bridge structure will be painted as part of the proposed project, which will require sand blasting to remove any rust and old paint. The contractor will prepare a plan to prevent all paint and sand blasting material from entering the MFFR. The staging area located on the south-east quadrant will likely be used by vehicles and the compressor used for the removal and painting of the bridge structure. It is estimated that the bridge painting will take approximately 40 working days, which is equal to 2 months.
