Louth Navigationとは 意味・読み方・使い方

The Louth Navigation canal ran 11 miles from Louth to Tetney in Lincolnshire, England, through 8 locks. 6 of the 8 locks were built in an unusual way with the sides of the lock chambers consisting of 4 elliptical bays, this was apparently to make them stronger. Some of these locks still survive, the remains of one can be seen at Alvingham. The two other locks had conventional straight walls. The canal obtained its Act of Parliament in 1763 (although the canal had been planned as far back as 1756) and construction started in 1767. The canal opened in 1770. The canal cost £28,000 to build and was able to carry seagoing boats.
