Massive preparations are here shown for a bridge in Piru Gorge. The slope of the huge fill is paved to protect the embankment and piers are being built through boxes extending down to the foundations.

Like oriental shrines extending up the rugged canyon in groups these bridge piers looked when this photograph was made of the construction projects along the Ridge Route Alternate in Piru Gorge. Four bridge sites are visible in the picture as indicated by arrows.

Shimmying tidal flats doing an earthquake waltz were responsible for most of the damage done to highways in the Long Beach coastal area. This image shows slab displacement southeast of Huntington Beach near the Santa Ana Overflow Channel.

Shimmying tidal flats doing an earthquake waltz were responsible for most of the damage done to highways in the Long Beach coastal area. This is a view on Hathaway Avenue the morning after the quake showing how the fill slope cracked badly while the sturdier macadam highway was but little affected.

Shimmying tidal flats doing an earthquake waltz were responsible for most of the damage done to highways in the Long Beach coastal area. This shows Anaheim Bay Bridge showing distortion of the southerly approach by the sinking of a portion of the roadway. This bridge was shortened 9 inches by pressure from the approaches.

Taking to the Hills to avoid dams and lakes that will occupy the bottom of San Gabriel Canyon engineering forces are completing construction of new highline highway along steep mountain slopes of Angeles National Forest in cooperation with city, county and U. S. Government departments.

In Glendora the Foothill Boulevard was graded 60 feet wide and surfaced with 40-foot concrete pavement for 1.5 miles, in cooperation with Los Angeles County by which the State paid approximately $50,000.

Direct Arterial Route between Los Angeles and Pomona now under construction is shown by heavy black line. Lighter black lines indicate existing Foothill Boulevard and Valley Boulevard Routes.

Ideal grade separation plan of the new Los Angeles arterial permits six miles of modern high standard boulevard through suburban area without a grade intersection. Monterey Pass Road is crossed by an overhead sructure and Coyote Pass traffic is handled by a partial separation as shown above, cars moving in southwesterly direction being diverted through an underpass to prevent a lefthand turn across traffic.

Mission and Moderne at once. The graceful lines of the new Monterey Pass overhead bridge structure blend twentieth century engineering with the historic background of the southland.

Many big cuts on Los Angeles-Pomona Highway permit a direct route through hills and wide oiled shoulders give additional width to broad traffic lanes.

The newly improved link of State highway through the city of Anaheim. Newly paved and widened North Los Angeles Street, now a fine broad thoroughfare. At right is the old street narrowed by encroachments and obstructions.

A cutting moment is pictured above when Governor James Rolph, Jr. severed the tape across North Los Angeles Street in Anaheim officially opening an improved link of the Coast Highway through the city. At Governor Rolph's right is Assemblyman Ted Craig of Brea and at his left (the smiling gentleman holding a cane and cigar) is State Highway Commissioner Philip A. Stanton of Anaheim. Others in the group are Mayor C. H. Mann, Secretary Reid of Anaheim Chamber of Commerce, William McCarthy, Secretary to the Governor; Director C. W Hintington of Professional and Vocational Standards, and District Engineer S. V. Cortelyou. - Photo by Long Beach Press Telegram.

Beautiful Vistas of high mountain scenery and a great expanse of virgin National Forest back of Mt. Wilson will be made accessible to the Los Angeles metropolitan area in September by completion of the last link of the Angeles Crest Highway.

The 65-mile loop tour that will be made available by the Angeles Crest Highway connection with San Gabriel Canyon highway is shown in the pictorial map by artist Newton Pratt.
