Drivers trying to get across the Day Island Bridge will have to make do with one lane as crews work to replace a deteriorated 382-foot sewer pipe beneath the bridge.
Work on the $300,000 project began this week and will continue through mid-May, according to Pierce County Public Works and Utilities.
The original pipe was installed in 1972 and a temporary bypass system was installed in May 2012 after small holes caused by corrosion were found in the pipe.
Workers will take out the old pipe and replace it with a 6-inch iron pipe beneath the bridge deck. The new pipe will be lined with corrosion-proof coating and insulated with rigid foam and polyethylene jacket, the county said.
The bridge spans Day Island Inlet and the Burlington Northern Santa Fe railroad tracks.
