East Los Angeles Interchange

East Los Angeles Interchange Complex

Golden State Freeway Santa Ana Freeway	Santa Ana Freeway	Santa Monica Freeway San Bernardino Freeway	Pomona Freeway

World's Busiest Freeway Interchange

More than 430,000 vehicle pass through this interchange daily.

Overview of the East Los Angeles Interchange from a USGS topographical map. There is a small error on this map denoting the San Bernardino Freeway west of I-5 as SR-10. It is in fact Route 10, not really a part of I-10 but not a State Sign route.

Closer views of the East Los Angeles Interchange Complex.


San Bernardino Split. The purple line marks the El Monte Busway. The flyover ramp from I-10 West to US 101 South, originally constructed in 1955, was removed in 1995 due to the redundancy of the same connection at the I-5 / I-10 junction and seismic retrofit. SR-10 is an error, it reflects Route 10, not I-10.	I-5 / I-10 Junction. Purple areas east of I-5 mark the area of I-10 that was reconstructed in the early 1970's. The purple line west of I-5 marks the El Monte Busway.

Main East Los Angeles Interchange. The Santa Ana Freeway (US 101 and I-5) is the only roadway that flows all the way through this interchange without the use of ramps.

Map showing the beginnings of the modern interchange. Dates to 1959.
	San Bernardino Split and I-5 / I-10 Junction.

	Location of the East Los Angeles Interchange. Ramps shown as proposed leading from US 101 at Murietta Street were to be the beginning of the Olympic Parkway. These ramps were never constructed. However, the underpass from North US 101 to westbound Olympic Parkway was constructed. It remained a bridge over nothing for many years. Traffic from Westbound SR-60 to Westbound I-10 now use the underpass. I-10 is the modern construction of what was to be the Olympic Parkway so, it may have took many years, but the bridge finally is used for the purpose it was designed for.
