California Interstate 5 (I-5) Grapevine Ascent at 300 MPH
Welcome to one of the world's busiest commercial thoroughfares. Fasten
your seatbelt as you ascend California Interstate 5's legendary Grapevine
grade at a blistering 300 MPH (video simulation Mr. CHP officer, thanks for
wondering). Try the full-screen, HD view for visual detail.
Home to wild weather, treacherous winds, blanket Tule fog, and overheated
vehicles, ascents and descents are always full-attention grabbers, make no
mistake about it.
The south-bound journey begins at the southern end of California's Central
Valley in the In-N-Out Burger parking lot off Laval Road (slightly north of
the ascent), and finishes over Tejon Pass summit, just past Gorman.
Note the high truck count and their occasional maximum-surprise lane
Near Tejon Pass summit, the camera drifts to the slow lane to catch the
elevation sign and almost catches a five-foot section of tire tread laying
in the lane - narrowly missed by swerving right onto the roadway's shoulder
at freeway speed.
The descent into Santa Clarita Valley is also spectacular, but that is
Enjoy the golden July hills, laden with cattle, oil, and landslide benches
- golden in the summer, green in the winter.
Finally, this great video has a good description of what the Grapevine is
