From October 3, 1955, through 1959, a total of 4 seasons and 156 episodes aired in syndication. A ZIV Television Production, Highway Patrol, starring Broderick Crawford, was a success and continues to air to this day. The show was filmed as realistically as possible, which included the support of the California Highway Patrol for the first part of the first season. To create as much realism as possible, the show filmed on actual locations throughout Southern California. Most of the shows were filmed in 2 days, a few in 3. One day was spent at the studio filming interiors and/or using the studio "backlot," what there was of it. The other day (or two) were spent out in the field. In the 156 episodes, there were over 600 locations used. In 2014, "Highway Patrol Locations Then and Now" was published. It showed most of those locations, utilizing then images from the show and now shots taken by the author. Many of the locations have not changed or have changed very little. Other sites have changed greatly. But, not all locations were shown. This book shows more of the locations which were not included in the first book and also corrects some errors which appeared in it.
