1973. BROCHURES. (DOÑANA NATURAL PARK). MARTÍNEZ IZQUIERDO, LUIS (engineer):. PROJECT FOR THE CA-624 BYPASS, FROM SANLÚCAR TO BONANZA, C-442 HUELVA-CADIZ DIRECT HIGHWAY. THE DEVELOPMENT HIGHWAY. A set of documents comprising the cost estimate and plans for the highway bypass (including longitudinal and cross-sectional profiles, drainage works, a pier, intersections, etc.), submitted to the Cádiz Provincial Highway Authority. It contains 14 folders with profile maps and another set of documents divided into three main sections: project report, specifications, and construction budget. All of these are photocopies of the typewritten originals, and the plans are reproductions of the original project, certified with the date and signature of the chief engineer.

This would require renovating the pier to accommodate large ferries, as its capacity would determine the road’s service—whether it could handle only passenger cars or also heavy vehicles. The project itself mentions the possibility, in the future, of building a bridge over the Guadalquivir River, should traffic demand it. The project specifies that the highway would be the C-442, but it essentially revives a proposal from 1973 that was not new to the region; as early as the late 19th century, the possibility of connecting these two provincial capitals had been studied, and the many economic benefits it would bring to the region had been highlighted. Even today, they remain the only Andalusian provincial capitals not connected by a highway, since for more than a hundred years, various proposals—including this one—faced opposition from those who objected to a highway that would cut through the marshes and dunes of Doñana National Park, the...
