Construction work on the road tunnels under Plaça de les Glòries between Calle Badajoz and Calle Castillejos in Barcelona.
Popularly known as Plaça de les Glòries, the Plaça de les Glòries Catalanes road junction is located in the Sant Martí district on the border with the Eixample district. Three of Barcelona's most important avenues converge here: Diagonal, Meridiana and Gran Via de les Corts Catalanes.
BIMSA terminated the contract signed with the construction company UTE Túnel Glòries for the execution of the road tunnel works in April 2017.
Since then, the "Modified Project No. 1 of the executive project for the road tunnels in Plaça de les Glòries between Calle Badajoz and Calle Castillejos" has been updated to include both the work carried out until the termination of the aforementioned contract and the new part pending execution.
The work pending on tunnel 1 (Plot 3) comprised the civil works' section from the middle of Shaft 2 to the Claperós collector crossing at kilometre point (Pk) 0 + 552.5 and included the execution of underpass 3 under FMB line 1.
