WESTPORT — Greens Farms Railroad Station’s parking lot No. 1 will be closed Friday night, and officials warn that any vehicles left there after 7 p.m. will be towed — at the owner’s expense.

The lot is being closed to clear the way for the town’s collection of household hazardous materials on Saturday.

The program for safe disposal of potentially dangerous products and chemicals will take place from 9 a.m. to 2 p.m. Saturday at the rail depot’s parking lot off New Creek Road.

The parking lot will remain off limits until 5 p.m. Saturday, according to the announcement from police and public works officials.
