The large lock at the Hiram M. Chittenden Locks in Ballard will be closed to all marine traffic from 8 p.m. on Nov. 8 until 5 p.m. on Nov. 22 for routine maintenance.

The small lock will still be available for vessels less than 115 feet in length and 26 feet in width throughout eh large lock maintenance period.

For the week preceding the large lock closure, Nov. 1-8, and for one to two weeks after, only the west (lower) chamber will be available for lockages. The chamber is 325 feet in length and 80 feet in width. This allows crews to pull the east end gates of the large lock for replacement of the pintle bearings and for inspection, cleaning and repair of the gates for the first time in 20 years.
