A busy stretch of the Long Island Expressway in Nassau County is among the top 100 congested areas in the U.S. interstate highway system, according to a new report.

The American Transportation Research Institute in Arlington, Virginia, puts a section of the LIE at Shelter Rock Road at No. 90 on its annual list of top 100 highway bottlenecks, made public this week.

At peak periods, the average speed at Shelter Rock Road in North Hills was 36 mph, the institute’s study said.

Robert Sinclair, a spokesman for AAA New York, said the Shelter Rock Road traffic jams might be partly due to the presence of one of the area’s largest employers, North Shore University Hospital in Manhasset.

The new study only found one New York City spot on the top 100 list: the point at which the Gowanus Expressway meets the Belt Parkway in Brooklyn, where the average speed in peak traffic was 31 mph, the report said.

The worst in the nation, according to the institute, was Interstate 285 at Interstate 85 in Georgia, where the average peak speed was 26 mph.

The institute is affiliated with the American Trucking Associations, which represents 35,000 trucking companies.

Its bottleneck survey, which began in 2002, now includes 250 highway locations and uses GPS data from the trucking industry.

The institute said its surveys improve planning for trucking companies and the clients for whom they deliver.

The paucity of chokepoints the study identified in and around New York City surprised the AAA New York spokesman.

For example, he pointed to a 2015 survey of the 50 worst highway bottlenecks by the Washington, D.C.-based American Highway Users Alliance that found nine in the New York City area, including what it called “the notorious Lincoln Tunnel” and I-95 from Manhattan across the Bronx.

However, the new study is timely, given that both President Donald Trump and congressional Democrats are proposing huge infrastructure investments, Sinclair said.

“If this study helps to delineate those locations that are in need of help I think it’s very useful but, again, I am kind of surprised,” Sinclair said.
