Highway set to reopen less than two weeks after deadly collapse in Philadelphia

Workers were putting the finishing touches on an interim six-lane roadway that will serve motorists during construction of a permanent bridge.

Crews worked around the clock and were poised to finish ahead of schedule. The interstate was scheduled to reopen at noon, according to the governor’s office.

The elevated section of I-95 collapsed early on June 11 after a tractor-trailer hauling gasoline flipped on an off-ramp and caught fire.

State transportation officials said the driver, who was killed, lost control around a curve. There were no other deaths or injuries.

The closure of an important commercial artery snarled traffic in and around Philadelphia and threatened to raise the cost of consumer goods as truckers were forced to detour around the area.

State and federal officials pledged quick action to minimise the economic impact and inconvenience.

To get I-95 operating again as quickly as possible, workers used about 2,000 tonnes (1,814 metric tonnes) of lightweight glass nuggets to fill the underpass and bring it up to surface level, then paved over to create three lanes of travel in each direction.

President Joe Biden joined Pennsylvania Governor Josh Shapiro on a helicopter tour of the site a little more than a week after the collapse and praised the design as “incredibly innovative in order to get this work done in record time”.

With rain threatening to delay the reopening, a truck-mounted jet dryer normally used to keep moisture off the track at Pocono Raceway was brought in to keep the fresh asphalt dry enough for lines to be painted.

The 24-hour construction work was live-streamed, drawing thousands of viewers online.
