Shown here, the Old Road nears Magic Mountain Parkway. Part of the divided highway is visible here as well. Behind, old US 99 followed the alignment of I-5 to Lyons Avenue / Pico Road.

The road leading to the east is currently Magic Mountain Parkway and was the 1926-1930 alignment of US 99. The road leading to the south is the north end of the Newhall Alternate (US 99) completed in 1930. The white road leading to the west is the alignment the Ridge Route took. At the 1059 mark, it went north over the 1916 bridge that has been gone since 1928. I-5 is situated just east of the north-south road.

Saugus Junction in the early 1970's.

That section, which is shown below, was widened to a four lane highway, as shown here in 1949. The next photo was taken near McBean Parkway looking north in 1997.

This was also where the Ridge Route joined US 99. Now, SR-126 joins into I-5 to Castaic Junction.

The photo below shows I-5 under construction from Magic Mountain Parkway to just beyond Castaic Junction.
