Metro Vancouver's TransLink Board revisits the issue of traffic safety on the notoriously narrow and busy Pattullo Bridge crossing again on Thursday.

The board will look at possible options for the four-lane bridge, which crosses from New Westminster to Surrey, B.C., including reducing the bridge to three lanes and creating a counterflow lane much like Vancouver's Lions Gate Bridge.

Other solutions include the installation of a centerline barrier to separate opposing lanes of traffic, banning large trucks from crossing, and the possibility of building a new bridge altogether.

The staff report on the bridge is expected to include results of technical work that began in 2005 and is the latest chapter in a years-long debate about how to resolve safety concerns at what is commonly known as the Lower Mainland's deadliest bridge.

More than twenty people have died in fatal crashes on the bridge since 1990.

A centerline barrier was previously approved for the bridge, but officials said installing it was more difficult than expected.

The board is not expected to vote on the issue today. A full report on the entire Pattullo corridor, including the on and off ramps into Surrey and New Westminster, is due to be released in July.
