SH7877 : Underneath the arches
taken 1 year ago, near to Gyffin, Conwy, Wales

Underneath the arches
I have no idea what these were intended for but they are below the A547 and the approach to the Conwy Road bridge.
Conwy Road Bridge
The new road bridge was built in 1958 and originally carried the A55, until the Conwy tunnel was built in 1991. The bridge now carries the A547 across the Afon Conwy, carrying mostly local traffic.
