Mumbai-Ahmedabad Bullet Train project work has reached another engineering milestone in Gujarat. A 130-metre steel bridge span now sits over Indian Railway tracks. This is reported by the railway transport news portal Railway Supply.

The launch took place near Tralsi village in Bharuch district, as reported by ETInfra. With this section in position, 230 metres are now complete. The bridge’s planned length is 330 metres.

The bridge crosses Dedicated Freight Corridor Corporation tracks between Surat and Vadodara. These tracks are on the Western Dedicated Freight Corridor. It is a three-span structure. The design combines a 100-metre and 130-metre continuous span. In addition, it includes a separate 100-metre simply supported span.

The 130-metre steel bridge span was shifted into place on May 16, 2026. It is about 18 metres high and 15.5 metres wide. It weighs approximately 2,900 metric tonnes.

In March 2026, engineers erected the 100-metre simply supported span at the construction site. That section weighs around 1,500 metric tonnes. The remaining 100-metre continuous span weighs about 1,600 metric tonnes. It will also be assembled on-site. That final 100-metre continuous span is needed to complete the 330-metre bridge structure.

The full Gujarat steel bridge will then weigh around 6,100 metric tonnes. Its steel components were produced at a workshop in the Karbon Factory. The factory is in Umergaon, Gujarat. The structures have been designed for a service life of 100 years.

For the 130-metre span, construction teams assembled the section on temporary trestles. The trestles stood 14 metres above ground level. The work used around 1,21,373 Tor-Shear Type High Strength bolts. Also, the section used a C5 painting system and metallic bearings.

The span was moved using an automatic system fitted with two semi-automatic jacks. Each jack can deliver a pushing force of 250 tons through mac-alloy bars.

The bridge launch took place while freight tracks remained active. It required coordinated temporary traffic arrangements. At the same time, these measures supported safety and precision during the operation. The phased work also helped limit disruption to freight movement on the corridor.

The wider bullet train corridor requires multiple steel structures along its route. In Gujarat, 14 of the 17 planned steel bridges have now been completed. Across the full Mumbai-Ahmedabad Bullet Train corridor, project plans include 28 steel bridges in total.
