Railway Bridge 5+078 is one of the bridges designed for the Segment A (Makkah – Jeddah) of Al Haramain High Speed Rail Link between Makkah and Madinah in Saudi Arabia. It 5+078 consists of two parallel structures carrying double and single track respectively. The span arrangement is the same for both structures: 15 spans 29+2x36.5+27+2x34+2x36.5+29+23+29+3x36.5+29m long, with a total length of 489.5m from station 4+837.400 to station 5+326.90 (double track axis).

Between pier P9 and P10 a simply supported span is provided, and the final section, from pier P10 to abutment A2 is 167.5m long.
