The links below will help you avoid some of the bans on HGV traffic in Spain, the web sites are from the Spanish Ministry of Interior and the Basque Regional government so should be reliable.
The information IS NOT a comprehensive list of all bans in Spain as apart from Pais Vasco (Basque) it does not include the bans imposed by various regions such as Andalucia, Castille La Mancha etc …from time to time.
National Bans: http://www.dgt.es/portal/es/informacion_carreteras/restricciones/ In Spanish.
Pais Vasco: http://www.trafikoa.net/public/wps/portal/trafico/kcxml/04_Sj9SPykssy0xPLMnMz0vM0Y_QjzKLd4s3cncBSZnFO8ZbeulHogt5IoR8PfJzU_WD9L31A_QLckMjyh0dFQHfufGr/delta/base64xml/L0lDU0lKQ1RPN29na21BISEvb0VvUUFBSVFnakZJQUFRaENFSVFqR0VBLzRKRmlDbzBlaDFpY29uUVZHaGQtc0lRIS83X0ZfNTkxLzE!?WCM_PORTLET=PC_7_F_591_WCM&WCM_GLOBAL_CONTEXT=/wps/wcm/connect/Trafico/CGTE_Medidas/02.-INFO+GENERAL+-+Medidas+ingles_es In English by month.
