The 15-foot-wide hole has been stabilized but traffic is being diverted because of the presence of gas mains under the road in the area, police said.
The hole is also about 50 yards from the main entrance to the Mack Trucks facility. Mack workers are being diverted to the Oxford Drive entrance of the Allentown Recycling Center and then to the rear entrance of the Mack facility, police said
The current sinkhole isn't the first one in Allentown. Another opened 6 months ago, as you can see in the video above. In 2013 a large sinkhole threatened a family home in Bethlehem Township. (video below)
