AREA TO TRAFFIC, CONTRACTOR SHALL PROVIDE STEEL PLATE OR OTHER MEANS OF PROTECTION APPROVED BY THE
ENGINEER FOR THE ANTICIPATING TRAFFIC LOADING. CONTRACTOR SHALL HAVE STEEL PLATE OR OTHER APPROVED
MEANS OF UTILITY PROTECTION ON HAND PRIOR TO OPENING UTILITY TRENCHES WITHIN THE DRIVABLE SURFACES OF
TOW PATH OR TRANSIT ROUTES. CONCRETE COLLARS MUST BE CONSTRUCTED AT PVC DRAIN BASINS PRIOR TO
EXPOSURE TO TRAFFIC OR CONSTRUCTION LOADING.
