THE OLD SPANISH TRAIL TRUNKLINES AND TRIBUTARIES The Old Spanish Trail still has difficult sections. It follows a route of great attraction, also a route of great engineering difficulties. But all the states are building. During 1924 construction over numerous natural barrier sections will be finished and comfortable travel conditions afforded. Thanks to the organized efforts of the Old Spanish Trail membership and of the engineers and highway officials, it is even now built and well maintained on eighty-five per cent of its long mileage. Inquiry at chambers of commerce and motor clubs along the way will provide dependable local information. If the traveler is interested in great construction works he will find much to compensate him as he travels along.
