PEMCO Insurance Poll: New 520 bridge may take a toll on alternate routes



​​SEATTLE – If the state legislature puts a toll on the Evergreen Point Bridge (SR-520), about one-half of Puget Sound-area drivers will simply find alternative ways around Lake Washington, a move that could spell big trouble for traffic congestion, a PEMCO Insurance poll reveals.

According to PEMCO's survey of drivers in the Puget Sound region, 51 percent of the respondents said they would avoid the 520 bridge if tolls were put in place. Only 11 percent report they would seek carpool options and even fewer respondents (6 percent) say they would take the bus in response to mandated tolling. These findings suggest that drivers will see a surge of traffic on alternate roads because of bridge tolls.

"Most would agree that the 520 bridge needs to be replaced," said PEMCO spokesperson Jon Osterberg. "Tens of thousands of cars cross the bridge daily. But if drivers choose not to use the bridge when it's tolled, where will those vehicles go, and does that come at a cost to other roads?"

PEMCO's results show that despite drivers' intentions to use the 520 bridge less often, they are not expressing a willingness to adopt behaviors that will reduce traffic congestion elsewhere. Nearly one-half (47 percent) of respondents say they would use I-90 more often, and one in four (24 percent) would drive north around the lake to avoid 520.

When asked what they would do if both the 520 and I-90 bridges are tolled, drivers' propensity to change behaviors is even lower: only one in 10 would carpool more often, just 4 percent would ride the bus, and 41 percent indicate they would not make any changes to their driving habits.

PEMCO's poll also gauged residents' willingness to make other changes like move residences, telecommute, or change jobs as a result of bridge tolling. Less than 3 percent indicate they would pursue any of those options.
