Bridge No 115
(Folly Bridge)


Road bridge over railway at Tring Cutting. Circa 1837 by Robert Stephenson for the
London and Birmingham Railway Company. Brown brick with stone impost bands, skewbacks,
cornice, and parapet copings. Northern parapet rebuilt for safety reasons in red brick
with triangular section concrete copings. A long narrow three-arched bridge with
working controlled by traffic lights on the B488 road, where it crosses the great
Tring Cutting, 2½ miles long and here about 50ft deep. A higher 7-ring segmental arch
in middle over trackbed with slender rectangular pierat foot of earth slope on each
side, and tall opening through each pier with round arched head and bottom. Slightly
lower segmental 7-ring side arches to abutments buried in earth slope. Wide unmoulded
stone cornice at roadway level with brick parapet and rectangular terminal piers with
weathered stone copings remaining on S side. The cutting was made necessary by
Stephenson's decision to have a maximum gradient of 1/330 on the line, and there is a
well known lithograph by J C Bourne showing an army of navvies excavating it. The
line was opened 9 April 1838. The county boundary withHertfordshire follows the
centre-line of the road over the bridge. (Leleux(1976)13-15).
