So we’re not talking many fatalities. There are quite a few crashes out there. When a crash occurs along Route 1, there is no room for maneuverability on the main line; so, it automatically incurs a roadway closure of at least a lane, possibly two lanes and that diverts traffic onto the frontage road. At that point you do get cut through traffic of people trying to get around the service roads, going out through the neighborhoods in that case.
The roadway will be wider, so you’ll have two travel lanes on mainline Route 1 in each direction. You’ll have five foot inside shoulders and 12-14 foot outside shoulders. That makes it easier to actually move traffic around an accident or even get traffic or disabled vehicles off the roadway onto the shoulder to maneuver around the crash site.
