Originally planned as long ago as 2003, the project was subsequently drafted in 2006 but now it has incorporated modifications in order that any possible flooding from the Gros Torrent is avoided. Similar to other roundabouts on the Via Cintura ring road, this elevated option has been taken instead of tunnelling, which was dismissed because of the proximity of the waterway.
The environmentalist group GOB has voiced its opposition to the roundabout as has Més, the socialist-greens political grouping. GOB has held a meeting with the councillor responsible for land, Mauricio Rovira, in order to find out more about a project which it says is going ahead despite residents of El Molinar having a total lack of information regarding the project and its impact on the area.
Sr. Rovira, who has explained that an original plan for a bridge with roundabouts to either side has also been dismissed because it would have had more environmental impact, has rejected GOB's complaints, pointing out that the environmentalists had not made any challenges to the project when it was twice put out for public consultation.
As for the objections of Més, the councillor has noted that it abstained when a vote on the project was taken at the Council, unlike its voting against other construction projects, such as those to do with the so-called second ring road.
