Crossings
The river has some 20 road crossings, including some medieval stone bridges, such as the crossing at Greystone Bridge near Lawhitton: this arched stone bridge was built in 1439. The lower Tamar is spanned by the Royal Albert Bridge (1859), the first crossing of the lower Tamar, and the Tamar Bridge, a toll bridge on the A38 trunk road. Both of these bridges are between Saltash (known as the Gateway to Cornwall) and Plymouth.
