The New York State Thruway Authority says they’ll be installing a new 270-foot-long pedestrian/bicycle bridge over the Thruway in Tarrytown tonight into Saturday morning, and it’ll require overnight lane closures and multiple traffic stops in both directions on today, weather permitting. The bridge will improve access to walking and biking paths on the Tappan Zee Bridge though motorists should expect delays as the work is being done. The work is expected to take about 10 hours, starting at 10pm Friday night and finishing by 8am tomorrow morning.
