The reduced curvature, increased sight distance, increase in minimum radii and reduced gradient will be conducive to snore rapid and pleasant travel on the lateral highway connecting the Bay area arterials and the lower San Joaquin Valley. As an added feature of safety and convenience, the traveled way ha.s been paved to provide a four-lane roadway in the vicinity of Station 155 where sight distance is limited due to curvature and a high bank an the inside of the curve.

Most Auto Mileage on State Highways Motor vehicles in the United States travel 250 billion miles each year, an average of 8870 miles per vehicle, according to an official report. The average vehicle, according to the State Highway Planning Survey, traveled 5000 miles last year on primary rural State highways, 1190 miles on secondary State highways and local rural roads, and 2680 miles. on city streets. However, there was wide variation in use of the different classes of highways by urban and rural residents. Vehicles owned in small towns were used principally outside of cities while residents of cities did more than 41 per cent of their driving on city streets, All vehicles except those in the largest cities used the State primary rural highways more than all other systems.

Rail haul was not feasible because of the size of the parts, and because rail branches ended over 35 miles from the site.

The intermediate piers each consist of 4 individual reinforced concrete columns on spread footings, while the end bents are supported on steel piles. The deck is a reinforced concrete slab approximately 74 inches in thickness, supported by 4 lines of girders. A 20-foot clear roadway is provided, with a 3-foot sidewalk on one side. The VPolf Creek bridge is a 3-span structure quite similar in design to the overhead structure. All the bridge footings are supported on steel H-piles. The intermediate piers were founded below the level of the creek which necessitated the construction of cofferdams and the pouring of concrete seals to exclude water from excavations during the construction of the piers. The bridge piers are a. single unit, rather than 4 individual columns as at the overhead. One end span is shortened to 52 feet while all other spans on both structures are 70 feet in length. The deck structure, hinge details, etc., are similar to those at the overhead. The steel understructtire of the deck is painted black while the railing is painted aluminum on both strue- tures, providing a pleasing color con- trast. (Continued on page 21)

U. of of impracticability of formulating a definite set of rules to cover such a wide range of conditions as are encountered in California. The coastal region, where such a standard may be conformed with, comprises only a small percentage of the State's area, while the majority of the State—valleys, mountains and desert—presents conditional problems that set a definite limitation on landscape treatment. In order to carry on a practical and perpetual program of roadside improvement it appears only reasonable that this fact be recognized and a more flexible translation of comprehensive projects be made. Generally speaking, landscaping in the valley region is necessarily confined to tree planting and the flattening of roadside ditches. (Treatment at structures and possibly town entrances are excepted.) Tree planting must be programmed three to five years apart in order to l~eep within a reasonable and nonfluctuating maintenance set- up. Valley projects then must necessarily be few and far between. The mountain regions offer oppor- tunities that are perhaps of more AF rFn esthetic and economic value than does the coastal. Although landscape fea- tures here are limited to grading, scenic turnouts, parking areas, topsoiling or general clean-up, ccny one or all combined definitely stand out as an improvement in roadside ap- peararice. To stipulate that all of these fea- tures shall be included in order to formulate a comprehensive plan is not always practical, since in many sections such as the semiarid foothills, clean-up of the right of way or the development of water and parking' space might have a great esthetic value and render a useful public service. In the higher altitudes more heav- ily covered with natural growth the intelligent use of topsoil on fills and flattened low cuts would bring about a rapid natural effect. Of course there are usually additional opportu- nities to provide other types of landscape treatment, but the point in mind is this—that even one basic landscape requirement is often hiah- ly desirable and worthy of appli- cation. Landscaping in the desert is obviously limited to harmonious grading and top soiling—perhaps top sanding would be more nearly correct. There Some comparable results of slope rounding are shown above.
