The Tappan Zee Bridge had only seven lanes, all of which were narrower than the current standard lane width of 12 feet. The new twin-span Governor Mario M. Cuomo Bridge will have eight wider general traffic lanes and shoulders. The shoulders of the new crossing will greatly reduce the traffic impact of disabled vehicles and accidents, which caused massive tie-ups on the old bridge. The incline approaching the main span will not be as steep, allowing large trucks to maintain consistent speed and reduce engine and braking noise. There will also be gently banked curves to further smooth traffic flow and reduce accidents. In addition, the new bridge is being built with dedicated bus lanes that have been shown to reduce travel times for all vehicles. In April 2016, cashless tolling went into effect, eliminating the need for eastbound drivers to slow down or stop and idle at a toll plaza.
