Construction Continues at Magic Mountain Parkway/I-5

Work has begun on the second phase of the 11-phase improvements to the junction of Magic Mountain Parkway and Interstate 5, according to an update provided by the City of Santa Clarita.

The city’s update included the following information:

The contractor, Security Paving Construction, 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. All necessary permitting has been secured from the various environmental agencies.

The construction of the storm drain box is over 90 percent complete. Construction is continuing underneath Magic Mountain Parkway west of The Old Road. Motorists are asked to allow extra time when traveling through the area during peak park hours. It is anticipated that construction of the box culvert will last another few weeks.

AT&T has begun the installation of new conduit lines between Tourney Road and the southbound I-5 off-ramp. The work is anticipated to be complete the end of August 2007.

In preparation for constructing retaining walls along the northbound I-5 off-ramp at Magic Mountain Parkway east to Tourney Road, clearing and grubbing was scheduled to begin at the end of July 2007.

Currently, they 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.
