NEW YORK - Another sign of the city's recovery from the pandemic is being marked Thursday as the High Line reopens to the public.

Strict social distancing rules will be in place and visitors will have to reserve a free, timed-ticket in advance.

Everyone has to wear a mask, and green dots are spaced six feet apart to keep visitors separated.

In another change, all guests must start at the southern end of the High Line at Gansevoort Street and can only walk north as far as 23rd Street, where they must exit. 

All other access points will be exit only, too. 

The section north of 23rd Street will remain closed for now. 

"On a busy day we can have about 50,000, we are going to have a fraction of that just to make sure people can feel completely safe and you have a lot of distance between you and anybody else up here," said The High Line Executive Director and Co-Founder Robert Hammond.

"Parks have been a place people are going to, and now we are so excited the High Line will be open up for people to stroll, enjoy, get healthy and enjoy our parks," said NYC Parks Commissioner Mitchell Silver.

The High Line will be open daily from noon until 8 p.m.
