August Update: I-5/Magic Mountain Parkway


Contractor Prepares to Build Retaining Walls

The city of Santa Clarita has provided the following update on progress for construction of the interchange improvements at Interstate 5 and Magic Mountain Parkway.

August 2007: The contractor, Security Paving, has completed removal of vegetation in preparation for constructing retaining walls along the northbound I-5 off-ramp at Magic Mountain Parkway east to Tourney Road. The next phase for the retaining walls will be the coordination with ExxonMobil for the placement of their new lines. This work will begin the end of August.

The construction of the storm drain box is nearly complete. Construction is continuing underneath Magic Mountain Parkway west of The Old Road. The traffic pattern entering and exiting the theme park has changed. It is anticipated that construction of the box culvert will last another six to eight weeks. Some delays have been encountered due to unexpected underground utilities.

The contractor, Security Paving, has begun working on the outlet structure that connects to the storm drain box that leads into the Santa Clara River. The City's on-site biologist, Entrix, is monitoring the construction activities on a daily basis. Diversion of the channel is complete and the dewatering operation will begin soon for the placement of the rip rap in the river.

AT&T is nearing completion of the installation of new conduit lines. There will be intermittent ramp closures for the southbound off-ramp for the tie-in of the new conduit to the existing lines.

Currently, we are working on Phase 2 of the 11 phases for these improvements. The anticipated completion of this phase is fall 2007. This phase includes constructing portions of freeway on-ramps and off-ramps, the majority of the drainage box, and retaining walls. During this phase, existing ramps and local roadways (Magic Mountain Parkway and The Old Road) will be open for vehicular traffic.

Please check the City of Santa Clarita's website at www.santa-clarita.com or the project hotline (661) 290-2297, for any extended major lane closures, detours, or news associated with this project.

Thank you for your continued patience and support!
