SEATTLE -- Washington State Department of Transportation officials on Wednesday announced that tolling on the 520 floating bridge will start at 5 a.m. on December 29.
WSDOT plans to use tolls to help pay for a new bridge project across Lake Washington that's estimated to cost more than $4 billion. Pontoons are already under construction to replace the 48-year-old bridge with a new six-lane structure.
The toll rates will vary depending on traffic and time of day, with rates scheduled to change 10 times a day during weekdays.
WSDOT said during the weekdays, there will be four different rate categories: peak morning/peak afternoon hours at $3.50 per crossing; the hours immediately before and after peak times at $2.80; a midday rate of $2.25; and evening/early morning rate at $1.60.
During weekends, three different rates (lower than weekday rates) will be charged. No tolls will be charged between 11 p.m. - 5 a.m. each day.
WSDOT also introduced four different options to pay the tolls electronically: the current Good to Go Pass Accounts, Pay by Mail, Pay by Plate and Short-Term Accounts. How a driver pays -- and in some cases what kind of vehicle is used -- will also affect how much a driver will pay.
Currently, drivers can purchase Good to Go Pass accounts, which offer the lowest toll rates. Tolls are automatically deducted from drivers' accounts, triggered by a Good to Go transponder installed in their vehicle.
Registered vanpools and transit vehicles are exempt from paying tolls on the 520 bridge, however, carpools and motorcycles will still have to pay the same toll price as regular vehicles.
WSDOT also said drivers will be charged more if their vehicle has more than two axles. For example, a two-axle car may pay $3.50 during peak weekday hours, while a three-axle vehicle would pay $5.25 during the same period. READ: How do I pay for 520 bridge tolls?
