ESH meaning in General ?

The Franklin D. Roosevelt East River Drive, commonly called the FDR Drive for short, is a 9.68-mile (15.58 km) limited-access parkway on the east side of the New York City borough of Manhattan. It starts near South and Broad Streets, just north of the Battery Park Underpass, and runs north along the East River to the 125th Street / Robert F. Kennedy Bridge / Willis Avenue Bridge interchange, where it becomes the Harlem River Drive. All of the FDR Drive is designated New York State Route 907L (NY 907L), an unsigned reference route.

The FDR Drive features a mix of below-grade, at-grade, and elevated sections, as well as three partially covered tunnels. The parkway is mostly three lanes in each direction, except for several small sections.

By law, the current weight limits on the FDR Drive from 23rd Street to the Harlem River Drive in both directions is posted 8,000 pounds (3,600 kg). Buses are not allowed to use the roadway north of 23rd Street because they exceed the road's maximum clearance and weight (although some do, including the MTA's QM7, QM8, QM8 Super Express, QM11 and QM25 express buses). All commercial vehicles (including trucks) are banned from all sections of the FDR Drive, except for a short section just north of the Battery Park Underpass where the northbound lanes temporarily merge with South Street.
