There was also a weir underneath the bridge which had a flash lock and later a "pen" lock. At the beginning of the 19th century this and the poor state of the bridge itself constituted a problem for navigation. Surveys discovered that the foundations were in a very bad state, and in 1815 an Act of Parliament was obtained to rebuild the bridge and remove the "Tackle and Works" underneath. The new bridge works were begun in 1824 and completed in 1827. A pound lock was established nearby in about 1832, which was removed in 1884. The bridge is Grade I listed.
