The Delaware River Port Authority is spending about $7.4 million for a new "zipper" traffic barrier on the Ben Franklin Bridge.

The DRPA board on Wednesday approved spending $7.376 million over five years to replace the existing, 15-year-old moveable barrier with a steel-and-concrete barrier like the one installed in 2010 on the Walt Whitman Bridge.

DRPA officials said the new barrier, to separate westbound and eastbound lanes of traffic, will allow wider travel lanes and be easier to operate and maintain.

The barrier will be purchased from Lindsay Transportation Solutions, of Vacaville, Calif.
