The downtown area of Greenwich consists primarily of Greenwich Avenue, a one way street that has many restaurants, boutiques, and antique shops. Chain retailers include Waldenbooks, Sax Fifth Avenue, the Gap, Restoration Hardware, CVS, and Subway. Retail space on Greenwich Avenue is very expensive. Greenwich Avenue is also somewhat unique in that it does not have traffic lights, but instead has individual traffic cops at each intersection directing traffic. Interstate 95 goes right through the town, and there are four exits from 95 in Greenwich. Route 1 also goes through town, as does the Merritt Parkway, although the Merritt Parkway is a considerable distance from the downtown area. Real estate in Greenwich is very expensive when compared to the national average, and is about on par with some nearby communities such as Darien and New Canaan. The high property values, however, cause property taxes to be very low.
The town has a beach on Long Island Sound, called Tod's Point. Originally, this beach area, which is on a peninsula and also includes picnic areas, was open only to town residents and their guests. However, a lawyer from nearby Stamford, Connecticut sued, saying his rights to freedom of assembly were threatened because he was not allowed to go there. The lower courts disagreed, but the Supreme Court of Connecticut agreed, and Greenwich was forced to amend its beach access policy. It now charges rather hefty fees ($10 per person and $20 per car) to go to the beach, and beach passes must be purchased at the town civic center, not at the beach.
