Here, you are getting two bridges for the price of one:
The Royal Albert Bridge (rail) built by Isambard Kingdom Brunel in 1859 and
The Tamar Bridge (road) built in 1961.
The Drill Hall cache is just a short walk from these 2 bridges.
The River Tamar forms part of the boundary between the counties of Devon and Cornwall.
My photos below, (apart from the Golden Gate), were taken over the past few years, the oldest being the ‘Bridges in the Mist’ 1984. More bridge photos can be seen in the Drill Hall log.
Lots more information on these two bridges can be found on the Web.
Many Thanks
