The Barcelona council has announced one of the biggest road-works programmes seen in the Catalan capital over the last ten years. Most of the works will take place in July and August when many of Barcelonas citizens are away on holiday. 67 streets are to be resurfaced with noise-reducing asphalt, including sections of one of the citys main thoroughfares, the Avinguda Diagonal. Tarmac is to be laid on the Ronda de Dalt ring road between Plaa de Karl Marx and the Ronda de la Guineueta Vella and improvements are underway on another major artery, the Via Augusta, between Carrer Pau Alcover and Plaa de l'Orient. Other road works include the remodelling of the Avinguda Vallvidrera and repairs to the road surface of Nus de la Trinitat. Improved access to the metro is also planned, with lifts being installed at several underground stations: Montbau, Sagrada Famlia, Maria Cristina and Zona Universitria.
