A new poll shows that by a slight margin, people in Seattle would prefer to repair the Alaskan Way Viaduct or replace the Downtown double-decker highway with a new span, The Seattle Times reports.

The survey also found that people weren’t crazy about Mayor Mike McGinn’s preferred alternative – tearing down the viaduct and dispersing traffic on city streets with enhanced transit options. However a clear majority would opt for something other than the $4.2 billion tunnel replacement project that has been approved by the Legislature supported by the City Council.

An Elway Poll found:

38 percent of Seattle voters preferred a new or repaired viaduct.

35 percent support the tunnel replacement.

Just 21 percent were in favor of surface/transit.

Opponents of the tunnel, which has the backing of the state, most of the City Council, the downtown business community and labor unions, are collecting signatures to try to put the issue before voters in August. However it’s not clear the initiative could actually stop the tunnel, which is a state project to replace the aging, earthquake-damaged downtown structure that carries more than 100,000 vehicles a day.

According to the Elway Poll, 55 percent of respondents wanted the chance to have a public vote on the city-state agreements concerning the tunnel.

The poll of 405 registered voters was taken March 22-25.
