Car 56 had been at MM 23 when the call came. Now, at better than four miles a minute, Beulah whipped past MM 45 with ten minutes yet to go to reach the scene of the accident. Light flurries of wet snow bounced off the canopy, leaving thin, fast-drying trails of moisture. Although it was still a few minutes short of 1700 hours, the last of the winter afternoon light was being lost behind the heavy snow clouds overhead. Ben turned on the patrol car's dazzling headlight and to the left and right, Clay could see streaks of white lights from the traffic on the green and blue lanes on either side of the quarter-mile wide emergency lane.
The radio filled them in on the movement of other patrol emergency vehicles being routed to the accident site. Car 82, also assigned to NAT 26-West, was more than one hundred fifty miles ahead of Beulah. Pittsburgh Control ordered Eight Two to hold fast to cover anything else that might come up while Five Six was handling the current crisis. Eastbound Car 119 was ordered to cut across to the scene to assist Beulah's crew, and another eastbound patrol vehicle was held in place to cover for One One Nine.
At mile marker 80, yellow caution lights were flashing on all westbound lanes, triggered by Philadelphia Control the instant the word of the crash had been received. Traffic was slowing down and piling up despite the half-mile wide lanes.
"Philly Control this is Car 56."
"Go ahead Five Six."
"It's piling up in the green and white," Ben said. "Let's divert to blue on slowdown and seal the yellow."
"Philly Control acknowledged," came the reply.
The flashing amber caution lights on all lanes switched to red. As Ben began de-acceleration, diagonal red flashing barriers rose out of the roadway on the green and white lanes at the 85 mile marker and lane crossing. This channelled all traffic from both lanes to the left and into the blue lane where the flashing reds now prohibited speeds in excess of fifty miles an hour around the emergency situation. At the same time, all crossovers on the ultra high yellow lane were sealed by barriers to prevent changing of lanes into the over-congested area.
As Car 56's speed dropped back below the two hundred mile an hour mark the cocoon automatically slid open. Freed from her safety restraints, Kelly jumped for the rear entrance of the dispensary and cleared the racking clamps from the six autolitters. That done, she opened another locker and reached for the mobile first-aid kit. She slid it to the door entrance on its retractable casters. She slipped on her work helmet with the built-in transmitter and then sat down on the seat by the rear door to wait until the car stopped.
