The crusher is used to recycle debris removed from the 7th Street bridge. The recycled material will then be used as a base for paving operations on the project. The crusher will be at this location for the next few weeks and work will take place in this location during the day between 7 a.m. and 5:30 p.m.

• A dirt embankment is currently in settlement on Seal Beach Boulevard adjacent to the fire station. This earth is being settled for the future Seal Beach bridge widening.
