Traffic in both directions on Marine Drive (U.S. Highway 30) will continue to be detoured through Mill Pond Village through Thursday afternoon, in the wake of a major water pipe failure. Motorists are asked to use alternate routes when possible.

The roadway was severely damaged when a 10-inch water main that passes under the 2800 block of Marine Drive, just west of the Hong Kong Restaurant, 2813 Marine Drive, failed sometime Monday night. The break was discovered at 6 a.m. Tuesday, when water was seen gushing up out of the road across from the Home Bakery, 2845 Marine Drive.

Astoria Public Works crews spent Tuesday replacing the north half of the 75-year-old cast iron main. They will replace the south half today. On Thursday, a paving firm will replace and repair the roadway surface, which was extensively damaged by the leak and subsequent excavations. Repairs are expected to be complete by Thursday afternoon.

Astoria Public Works Director Mitch Mitchum said the main served the old Astoria Plywood Mill for many years. It was turned off about 10 years ago, but put back in service recently to supply the new apartment building being constructed at Mill Pond Village. The main, which was buried about 12 feet deep, failed after developing a long crack.
