British Rail Midland Region London Rugby Line Bridge Number 113

Bridge Number 113 is an accommodation bridge over the railway at Tring Cutting, built around 1837 by Robert Stephenson for the London and Birmingham Railway Company. The bridge is constructed of brown brick and features stone impost bands, skewbacks, a cornice, and parapet copings. It has a long, narrow design with three arches that connect land divided by the extensive Tring Cutting, which is approximately 2½ miles long and about 50 feet deep at this location.

The central arch is a higher seven-ring segmental arch that spans the trackbed, supported by slender rectangular piers at the base of the earth slopes on either side. Each pier has a tall opening with a round-arched head and bottom. The side arches are slightly lower segmental seven-ring arches that lead to abutments buried in the earth slope. At roadway level, there is a wide unmoulded stone cornice, brick parapets, rectangular terminal piers, and weathered stone copings.

The cutting was created to accommodate Stephenson's decision to maintain a maximum gradient of 1 in 330 on the railway line, which was opened on April 9, 1838. A well-known lithograph by J.C. Bourne depicts the army of navvies who excavated the cutting. The south side of the bridge is located in Aldbury parish.
