GONZALES — Alligator Bayou Road in northwestern Ascension Parish will be closed from 8 a.m. to 6 p.m. Saturday for drainage work, officials said.

Crews with East Ascension Consolidated Gravity Drainage District No. 1 will install two drainage pumps at the Frog Bayou lock, drainage officials said in a news release issued Thursday.

The lock runs under Alligator Bayou Road and connects Frog Bayou with Bayou Manchac.

Crews also will install permanent piping under the roadway at that location, drainage officials said.

Frog Bayou drains the Bluff Swamp, which is on the western edge of East Ascension.
