 Tolls are going to be going up on the 520 bridge. The Washington Transportation Commission today voted to raise rates on the floating bridge by an average of 10%. These will go into effect when? August 15th. But they also reduced the variation in rates, now with six different prices to cross the water instead of eight, which rate, of course, is dependent on time of day. The commission says the new rates will ensure revenues will meet the financial obligations of bridge construction. Jeff Podula, Northwest News Radio.
