THROWBACK THURSDAY – In 1913, the Colorado Street Bridge was considered the largest bridge in the world completely made of reinforced concrete. This marvel of engineering rose 160 feet above the Arroyo Seco riverbed and spanned 1,467 feet also making it the longest and highest bridge of any kind in the Southwest. The bridge instantly became a vital link of the National Old Trails Route making Colorado Street (now Colorado Blvd.) a major thoroughfare for automobile travel in San Gabriel Valley and Los Angeles region. When the bridge opened to the public, parking was allowed on its full span. The speed limit was a mere 10 mph.
