Newhall Tunnel
South portal
By September of 1907, a tunnel bored a short distance to the west of the Beale's Cut was the preferred solution over deepening the cut. By January of 1909, the Highway Commission had approved plans for a tunnel. Funding would come from a Los Angeles County bond issue.
In December of 1909, the Board of Supervisors awarded the contract for the construction of the tunnel to E.E. Shaffer of Los Angeles. He was the successful bidder agreeing to do the job for $63,364 and have it done in less than six months. Actual work was due to begin on December 30, 1909. Plenty of blasting powder would be used for the job (from the LA Times of 12/28/1909).
60 men were employed and nearly 100 horses and mules were to be used. The men would soon have their own camp near the tunnel site where they could live. Very little machinery would be used. Schaffer believed that blasting powder and manpower would get the job done. There was also cutting and grading needed on both sides of the tunnel, making the whole project about 5100 feet in length. The contract did not include preparing the road surface. That would be done after the tunnel was completed.
On June 20, 1910, the Board of Supervisors granted Shaffer an extension from July 1 to August 31, 1910. A hard conglomerate needed more blasting work and would slow down progress. (LA Herald 6/21/10)
Due to changes in the tunnel specifications, cost was increased by $1816. Another extension for completion was given to Shaffer. The new date was October 31. (LA Herald 9/8/1910)
The Los Angeles Herald reported on December 6, 1910 that:
A. E. Loder, chief engineer of the highway commission, recommended to the board of supervisors yesterday that a bronze tablet bearing the names of the board, the contractor, the highway commission and himself be placed at the entrance to the Newhall tunnel in commemoration of its completion. He said the tablet could be secured at a cost of $125 or two tablets for $175. Loder said, however, that he thought one tablet would be sufficient. The matter was taken under advisement.
The tunnel was officially opened on December 21, 1910 (see article below).
The total length of the finished tunnel was 435 feet. It was 17 feet high and 17 feet 5 inches wide. It was about 200 feet below the summit and about 250 feet below Beale's Cut. The road grade was reduced from about 26 % through the Cut to about 6 % through the tunnel.
In 1917, this road became part of the State Highway system as Route 23. It would later become Route 6 and then Sierra Highway.
The light situation in the Newhall tunnel was a problem from the very start. Even the design of the tunnel took it into consideration. "As there was no artificial means at hand of lighting the tunnel it was quite necessary to make the actual tunnel as short as possible. For this reason, and in view of the fact that the material had stood in high vertical walls in the old cut 500 ft. to the east, the south portal was cut back 300 ft. and moved 60 ft. further north than otherwise would have been necessary. As now built the curved wall reflects some light through the tunnel to good advantage during the greater part of the day. On completion it was decided that the general appearance and the distribution of light through the tunnel could be improved by plastering. As a result of the plastering an attractive surface has been secured, and it is said that the distribution of daylight through the tunnel has been greatly improved." (Engineering Record, May 20, 1911, Vol. 63, No. 20, p. 567.)
In February of 1924, lights were finally added (Newhall Signal February 22, 1924). The lights were scheduled to be on day and night. However, soon after that in July of 1924, the lights were turned off "in harmony with the program of power conservation in Southern California, Division VII" (p7, California Highways, July 1924). The Newhall Signal of July 21, 1927, reported that "The interior of the Newhall tunnel is being painted a brilliant white, which much improves the light, and makes it much easier to drive through."
By the middle 1920's, the narrow tunnel was beginning to become a bottleneck to traffic. Motorists began demanding a solution. The number of automobiles registered in California in 1910 was 44,132. The number registered in 1927 was 689,902. The population in Los Angeles County increased from about 504,000 to 2,250,000. These increasing numbers were causing the bottleneck. On May 1, 1927, in a 24 hour period 24,480 autos carrying more than 75,000 people passed through the tunnel (from the Van Nuys News of 6/17/1927).
Early proposals were to construct a new tunnel or construct a road over the summit near Beale's Cut. Another idea was to construct a road from San Fernando up to the Pacoima Dam and then to Sand Canyon. From there it would go either up Mint Canyon or Soledad Canyon to the Antelope Valley.
In October of 1929, a contract was awarded to McCray Company of Los Angeles to change the alignment of the just north of the tunnel. Up to 1930, the road going north exited the tunnel and turned to the right (east) onto today's Clampitt Road. Then the road followed a wide loop to where it runs into today's Sierra Highway and continued on to Newhall. The new road would go straight north from the tunnel and run into the point where Remsen Road joins Sierra Highway, basically following today's alignment. That would shorten and straighten the road. The contract price was for about $70,000 for a length of 1.1 miles. It was finished in June of 1930 (info from California Highways and Public Works magazine).
But something still had to be done about the bottleneck at the tunnel.

Official opening on December 21, 1910. Article from the Los Angeles Herald of December 22. Note that a bronze tablet was placed at the south entrance to the tunnel. The completion of this tunnel was the end of the need for Beale's Cut.
The Los Angeles Rubber Stamp Company manufactured the tablet. This is from their Catalogue No. 20, circa 1920. Description from catalogue:
"Bull Metal Bronze Tablets - Machine cut and hand finished. The combination of metals in these tablets is made from a special formula of our own, the base of which is copper, it being best adapted for this class of work. Rich and artistic in color and very durable either for outside or inside exposure, improving with age. When the plates are ready for lettering they are from one-half inch to three-fourths of an inch in thickness, varying according to size of tablet. The letters are cut to stand out about 1/8 inch from a stippled background. Each letter is carefully cut and accurately finished by hand, requiring much time and care."
Title: "Newhall Tunnel" (1912)
This photo is dated 1912, two years after the tunnel opened, but it looks to me that the tunnel is still under construction. Everything looks freshly cut. This photo (and the next one) must have been taken in 1910 before the tunnel was opened.

World War 1 plans for guarding Los Angeles County included holding the Newhall Tunnel from invading forces from the north or northeast. A few men armed with rifles and machine guns could hold thousands of enemy troops at bay. At least, that's what the Los Angeles Police Department thought. They don't seem to be considering Beale's Cut right next door to the tunnel. To quote: "Newhall tunnel, in case word being received that the enemy was approaching from that direction, could be reached with autos filled with members of the Home Guard in forty minutes (it being understood that in a case of that kind the deputy sheriffs would not only close their eyes to speeding, but join in the chase themselves to guard the passes)." Los Angeles Times of April 22, 1917.

Photo 2 from the Coblentz family vacation. Just above the tunnel is a short wooden barrier to stop rocks from dropping directly on cars.
At a little over 17 feet wide and high, larger trucks had problems driving through the tunnel. Two trucks going in opposite directions would have a big problem.
