second may reflect the uneven terrain of the Kaims of Airlie that
would force a winding path on travellers.
Two
bridges are mentioned at Marykirk, one of them made of stone;
and further north in New Machar parish in Aberdeenshire there
is an intriguing "road to the mountains."
Pontoon
Bridge - Edward I
In
his campaign of 1303-4, Edward I ordered the construction of a
pontoon bridge which would allow Stirling Castle to be bypassed
by crossing the Forth downstream of the castle. There were ferries
but these would be inadequate to support an invading army.
Work
began at King's Lynn on this huge undertaking with timber and
other materials being brought in from all across England. Three
hundred pontoons were made and required 30 vessels to transport
them north.
It
is not known where it was used although it could easily span the
Forth upriver from Kincardine. It may have been near Alloa as
Edward, when he crossed it, spent time at Clackmannan. Oddly enough,
a contemporary chronicler says that the bridge was not used.
Used
or not, the bridge ended up in storage at Berwick until Edward
ordered it to be brought to Blackness and presumably Stirling
while the castle was invested.
When
it was no longer needed, it was broken up and the materials used
in various building works underway at that time.
It
may not have been the first time
a pontoon bridge was used in Scotland. Two coins dating from the
time of the Severan invasions of 208-11 show a pontoon bridge
and a fixed bridge which are thought to have crossed the Forth
and the Tay though it is not certain which river each one crossed.
Of the sites
surmised for the Forth one was at Queensferry and the other near
Alloa. The latter is interesting in view of the tradition related
by Jocelyn in his life of Kentigern who is said to have crossed
the Forth here by the Pons Servani. As Kentigern lived in the
late 500's, it is quite conceivable that a Roman bridge could
have survived until that time. See here
under Alloa.
