Over 6" Rain in Randolph

Light rain in the morning didn't bother, but the heavy rain that started about 1:00 ended work for the day. Over 6" of rain in flooded us out. The erosion control bituminous curb we installed on the north end helped contain much of the runoff in the abutment two area.



The pavement on the road on the south end of the bridge has deep ruts, so a lot of water ran by the drop inlets (drains) and eroded the gravel backfill along the west side of abutment one.

Some gravel washed down onto the concrete subfooting we placed on tuesday, but was for the most part well contained.
We had just placed the stone fill around the pier last Friday. Erosion around the pier and the work bridge was minimal.
A lot of wood debris and trees came down the river. Nothing got hung up on the work bridge. A large tree did get hung up on the scour sheeting just downstream of the work bridge.
