Inscription. This bridge was originally part of six spans which crossed the Santa Ana River on La Cadena Street between the cities of Colton and Riverside, California, in the early 1900's. In 1933 the bridge was relocated to Greenspot Road by the County of San Bernardino to complete construction of a road from the Greenspot area to East Highlands. This section of Greenspot Road was established by Mr. J.S. Edwards who owned many acres of oranges in East Highlands and Greenspot but had to truck his fruit some distance through Mentone and Redlands to reach his Gold Buckle Packing House in East Highlands. In July 1931, his employees cleared a five mile dirt portion of the road, saving nine miles of travel over the old route. Two years later the County took responsibility for Greenspot Road and improved it with pavement and placement of the bridge. In 1996 the City of Highland moved the bridge from Greenspot Road east of Alta Vista, to its present location at Aurantia Park. It was relocated as part of a street improvement and bridge replacement project. The new bridge across Plunge Creek was dedicated in 1997.
