GC-3 viaduct works: Lane closures and diversions in Las Palmas

Motorway repairs get under way on Gran Canaria

Waterproofing works on the Guiniguada viaduct, part of the GC-3 ring road around Las Palmas de Gran Canaria, began this Sunday with the closure of the northbound carriageway for the first fortnight of August. The work, which is being carried out by the Cabildo de Gran Canaria through its Department of Public Works and Infrastructure, will initially affect traffic heading towards Siete Palmas, Tamaraceite and the north of the island.

Vehicles travelling from the south will need to divert at Barranco Seco onto the GC-31, passing through the San José tunnels to reach the Avenida Marítima, and then continue towards Julio Luengo to head north. According to a statement from the Cabildo, the southbound closure will come into effect from 16 August and will run until the end of the month.

Essential repairs to a bridge lacking waterproofing since construction

The work involves waterproofing the two decks of the viaduct, a feature the bridge has lacked since it was first built. The intervention is considered essential to guarantee the conservation, safety and durability of this infrastructure, which carries more than 130,000 vehicles a day. In total, more than 18,000 square metres will be waterproofed across the two decks, with each carriageway expected to take between eight and nine days to complete.

The Cabildo has described the timeframe as a record, given that such work usually takes considerably longer. To achieve this, the Department of Public Works has agreed with the contractor, Lopesan Asfaltos y Construcciones, to double the number of shifts. This will bring the total to 20 specialised workers across the two shifts, when the norm for this type of work is usually no more than five or six operatives, the island corporation has confirmed.

Appeal for patience as August works get under way

Speaking at the start of the works, the Vice-President of the Cabildo and Councillor for Public Works, Augusto Hidalgo, explained that without this deployment, the work would have stretched on for three months. He also pointed out that August had been chosen because it is the month with the lowest volume of traffic on the roads all year.

“We are aware that these closures are going to put pressure on the lower areas of the city, so I want to urge the public not only to be patient, but also to inform themselves properly about which routes are open and the most viable alternatives before getting in the car,” he added.

Details of the project and alternative routes

The works include milling the existing asphalt layer, laying waterproofing asphalt membranes and replacing the expansion joints on both bridges. The Department of Public Works has allocated €2.2 million to this phase, which forms part of a wider project to resurface 11 kilometres of the ring road. That broader scheme, valued at €18.7 million, has been under way for several months and is being carried out at night.

The Cabildo is advising drivers to plan their journeys in advance, check the alternative itineraries and use public transport wherever possible to help reduce the impact on traffic throughout August.
