The Lothian Bridge is a road bridge in the Scottish town of Pathhead in the Midlothian Council Area . In 1971 the building was included in the Scottish List of Monuments in the highest category A.
history
Once a major trade route ran through a ford in the Tyne between Ford and Pathhead. With the increase in traffic in the 19th century, the construction of a bridge became necessary. The engineer Thomas Telford was entrusted with the planning . The Lothian Bridge was eventually built between 1827 and 1831.
The relatively long construction time is due to difficulties in the construction phase. For the foundation of the pillars, drilling was carried out during the planning phase, in which the depth of the bedrock was determined to be four meters. During the construction phase, an iron rod was then drilled 17 meters deep into the ground without hitting rock. It emerged that the previous drilling was wrongly interpreting large boulders as bedrock. Since these are unsuitable for the foundation of the pillars, the construction of foundations consisting of several layers of wood and material from a quarry on Craigleith was necessary. This incurred an additional cost of £ 2000. The total cost was £ 8,500.
description
The masonry viaduct is on the northwest edge of Pathhead. It leads the A68 ( Darlington - Dalkeith ) over the Tyne, which at this point forms part of the E15 ( Inverness - Algeciras , Spain). The Lothian Bridge spans the Tyne with five lined round arches with clear widths of 14.6 m and clear heights of 20.7 m. On both sides of the road there are footpaths that rest on more filigree segmental arches that protrude from the masonry like a dazzling work. They run out in pilasters along the pillars . Telford chose this construction to give the tall bridge such a slimmer appearance. However, it is criticized that the differences in the arc radii do not offer the viewer a point of rest. The Lothian Bridge has numerous parallels with the Dean Bridge in Edinburgh , which Telford designed in the same period.
