Phase 2 Nearly Complete At Magic Mountain Parkway Interchange

Finishing touches to be added in JulyMagic Mountain Offramp

The City of Santa Clarita released the following statement regarding the Magic Mountain Parkway / I-5 Interchange :

After three years in construction beginning in June 2006, the Interchange Improvements, Phase 2, will be final in July 2009. Over these past three years, the lead agency, the City of Santa Clarita, in partnership with Caltrans and Los Angeles County Department of Public Works, has completed the following work:


* Realignment and widening of The Old Road, approximately 4,000 linear feet.
* Widening of Magic Mountain Parkway between The Old Road and Tourney Road.
* Widening of all four ramps at Magic Mountain Parkway and Interstate 5.
* Completed new utility facilities for communication, water, and sewer; rehabilitated the existing sewer line; and relocation various utility lines by affected utility companies.
* Completed underground stormdrain concrete culvert and constructed a new outlet structure on The Old Road.
* Installation of new underground drainage facilities on The Old Road and Magic Mountain Parkway.
* Installation of new signal, lighting, and electrical system on The Old Road and Magic Mountain Parkway.

This major interchange improvement project will greatly improve mobility, enhance safety, help to alleviate congestion, and dramatically increase capacity of the interchange and local roadways. In addition, as part of the Green Friendly City, the City mandated that the Contractor use recycle materials, i.e., asphalt concrete, cement concrete, and fly ash as part of the construction of roadways and retaining walls.

We appreciate all the patience and support of the community during this project.
