Lock No. 28
Also known as: Deep Lock

Why it's listed
Lock No. 28, popularly called "Deep Lock," is a canal lock on the Ohio & Erie Canal at Peninsula, Summit County, Ohio. Built between 1825 and 1827, it is a standard mitered-gate lock of load-bearing masonry, faced in cut stone and concrete. Its chamber is 15 feet wide and 16 feet deep. That depth made it the deepest lock on the section of the canal between Akron and Cleveland, which is the source of its name. Like most other locks in the system, it was repaired with concrete around 1905. Both gates are now missing, though water remains in the chamber. The lock sits in carefully maintained park land within Deep Lock Quarry Metro Park, near the Old South Quarry. It is regarded as one of the best preserved locks in the Cuyahoga Valley, along with Locks No. 37-39 in Valley View. Its condition is recorded as very good, and the site is open to the public without restriction.
Significance in brief: At 16 feet deep, it was the deepest lock on the stretch of the Ohio & Erie Canal between Akron and Cleveland, which gave it the name "Deep Lock." Along with Locks No. 37-39 in Valley View, it is described as among the best preserved in the Cuyahoga Valley.
