Construction project of Footbridge in Lugo University Campus (Spain)

Footbridge over the main road N-VI in the kilometre 498, near the Lugo University Campus (Spain)

The footbridge crosses over the main road N-VI in the kilometre 498, near the Lugo University Campus (Spain). The footbridge joins the University Campus and a sport facility for the local basketball team, with the Miño river promenade.

The footbridge allows access also to the Miño Promenade for motorists that can park near one side of the footbridge and cross over the N-VI road, as well as students from the Campus. The footbridge is integrated in the existent net of paths around the campus and Miño River.

The footbridge has a plan configuration shaped like a three pointed star. The main span crosses over the N-VI Road, and joins with the access ramps in a central point. Each of the star “arms” is formed by two laminated timber beams, with an inferior deck forming a “U” shaped section along all the structure.

 

This way the beams act both as the main structural element and as railings for the pedestrians. Main span is 35.0m, and each ramp is 50m length, with a maximum span of 30m. Cross-section width is 2.50m measured between inner beam sides.

The pedestrian flooring is made or timber planks which are supported by transversal steel elements that provide bracing for the beams.

All the piers are shaped like triangular-cell, with two sides oriented towards the foundation plinths, and the top edge being the deck beam itself. There is a second type of vertical piers for the access ramps. Piers are designed using laminated timber.
