Alligator Road to reopen early Monday Alligator Road to reopen early Monday Advocate staff report March 06, 2013 Comments Ascension Parish officials planned to reopen Alligator Bayou Road at 5 a.m. Monday after shipping problems delayed the reopening, Ascension Parish President Tommy Martinez said Sunday afternoon. The work at Frog Bayou Lock/Alligator Bayou Road was originally scheduled to be finished Sunday night, but weather delayed the delivery of equipment being shipped from Florida, he said. The equipment is to be used to install drainage pipes connecting Frog Bayou and Bayou Manchac, Martinez said in a news release. Crews began working Saturday to build and install two 42-inch drainage pipes under Alligator Bayou Road. Two diesel engines will be used to drive hydraulic pumps in Frog Bayou capable of pumping 50,000 gallons of water per minute from Frog Bayou through the new pipes under Alligator Bayou Road into Bayou Manchac, said Allen Allred, assistant director and operations manager with the East Ascension Gravity Drainage District No. 1. The pumps are expected to help lower water levels in the Bluff Swamp Basin, officials have said.
