The collapse of the Twin Towers destroyed the Vesey Street bridge and heavily damaged the Liberty Street bridge. To improve pedestrian flow, a temporary bridge was built at Rector Street; a permanent bridge was built West Thames Street, one block south, in 2019, after which the Rector Street bridge was demolished. A temporary bridge at Vesey Street opened in November 2003 near the site of its predecessor, and was demolished by 2013 once a pedestrian tunnel was built under West Street. All bridges have elevators and ramps for disabled pedestrians, as per the Americans with Disabilities Act of 1990.
