Seventy highway structures were damaged. Numerous roads and city streets in the Sylmar-San Fernando area were made dangerous or impassable by ruptures. Railroad rails were distorted. This photo shows freeway compression of about 67.5 cm that occurred south of the Interchanges of Routes 5 and 210. The dip of the fault plane on Freeway 210 was inferred to be 12 degrees. Structural damage to highways and bridges from this earthquake centered in an area north of the city, which included the Route 5/210 Interchange and the Route 5/14 Interchange. Most of the major structural damage to highways was within 10 km of the earthquake epicenter.
