Other entries show postmile prefix followed by postmile to the nearest hundredth of a mile. Prefixes of R, M, and N refer to re-aligned routes. Prefix L refers to a section or route paralleling another route. When the route is on the deck of the bridge, the postmile is recorded at the beginning of the structure (i.e. the lowest postmile on the bridge). When the route goes under the structure, the postmile is recorded on the underpassing route where the structure is first encountered. All other measuerments in this publication are given in meters. Bridge Number The official structure number assigned by CalTrans. The Bridge Number Suffix carries information about the function of the structure. Blank Structure carrying two-way traffic C Center structure E Connector structure F Connector structure G Connector structure H Connector structure J Outer outer left K Left outer highway structure L Left structure of left inner structure M Burried Hazard or miscellaneous structure R Right structure or right inner structure S Right outer highway structure T Outer outer right W Drainage pumping plant Y Structure on State-owned and maintained connections no on main highway (may be closed) Z Access to private property or closed with no access OU "O" Indicates that the route is carried on the deck of the structure "U" Indicates a route crossing under the structure. O - Structure Name U - Roadway Under or Route Information When route traffic is on (O) the structure, the structure name is shown. When route traffic is under (U) the structure, the roadway name is shown, otherwise, miscellaneous route information is shown. iii October, 2018 LOG OF BRIDGES ON STATE HIGHWAYS Structure Types Code for main span type followed by approach span type (if different). First character (Material): Second & Third characters (Design): 1 = Concrete 01 = Slab 2 = Concrete continuous 02 = Stringer/Multi-beam or Girder 3 = Steel 03 = Girder and Floorbeam System 4 = Steel continuous 04 = Tee Beam 5 = Prestressed concrete 05 = Box Beam or Girders - Multiple 6 = Prestressed concrete continuous 06 = Box Beam or Girders - Single or Spread 7 = Wood or timber 07 = Frame (except frame culverts) 8 = Masonry 08 = Orthotropic 9 = Aluminum, wrought iron, or cast iron 09 = Truss - Deck 0 = Other 10 = Truss - Thru 11 = Arch - Deck 12 = Arch - Thru 13 = Suspension 14 = Stayed Girder 15 = Movable - Lift 16 = Movable - Bascule 17 = Movable - Swing 18 = Tunnel 19 = Culvert 21 = Segmental Box Girder 22 = Channel Beam 00 = Other City CalTrans alphabetic code for the city or government land within whose limits the bridge exists. The Alphabetic City Codes Table shows the full city names corresponding to these codes. Where a name is preceeded by an asterisk, it indicates a bridge on government lands not within any city limits. Bridge Length The length of the structure from paving notch to paving notch in meters. Width The out-to-out width of the structure to the nearest tenth of a meter. For through structures, the lateral clearance between superstructure members. For flared structures, the minimum deck width. No width is shown for non-grade-top culverts or structures not carrying vehicular traffic, such as underpasses or pedestrian overcrossings. Number of Spans The number of span in the structure. Upper-level spans of double deck structures are not included in this count. Min VC Over Roadway The minimum vertical clearance over the traveled way portion of the ROUTE in meters. In the case of arches, tunnels, through trusses, etc, where the minimum clearance does not give a true picture, an asterisk ("*") is shown after the clearance. In such cases, an accurate depiction of the available vertical clearance may be obtained from the structure clearance diagram which resides within the office of Structure Maintenance and Investigations. Sidewalk Widths The minimum width of left and right sidewalks or curbs, to the nearest tenth of a meter. Where this value is 1 meter or greater, the structure is considered to carry pedestrian traffic. iv October, 2018 LOG OF BRIDGES ON STATE HIGHWAYS Year Built (Original Construction) and Year Widened or Extended The year of original construction. For some older bridges, this may be an estimate. Permit Rating Permit ratings are shown for information only. They should not be used for permit issuance. The permit rating is usually a string of five characters showing permit capacity for 5,7,9,11, and 13 axle vehicles. Where a single character is shown, it represents an "administrative" rating. P Purple permit capacity G Green permit capacity O Orange permit capcity X No permit capacity Permit rating are for information only. They are not to be used for permit issuance.

E-mail: [email protected] Abstract Slender salamanders of the genus Batrachoseps achieve relatively high diversity in the Kern Canyon region at the southern end of the Sierra Nevada of California through high turnover of species with small geographic ranges. The status of several populations of Batrachoseps in this region is enigmatic, and both morphological and molecular data have suggested that some populations do not belong to any of the currently recognized species. Identification of species in this region is com- plicated by the apparent extinction of Batrachoseps relictus in the vicinity of its type locality in the Lower Kern River Canyon. Here we analyze a comprehensive morphological dataset to evaluate diversity in the Kern River Canyon region.

    2012 Bristlecone Chapter Spring and Summer Field Trips Please check our website for more details, updates and changes: www.bristleconecnps.org/events March 17, Saturday – Wildflowers, Cyptobiotic Soil Crust, Microbial Mats, and Tufa Encrustations in Poison Canyon. Leaders: Jane McEwen & Judy Breitenstein. This tour of Poison Canyon, which connects Indian Wells Valley and Searles Valley, will focus on the chain of Pleistocene Owens, China, and Searles Lakes. Besides looking for wildflowers, common and rare, we'll drive up into the hills to look at tufa limb casts of shrubs or trees submerged during the Pleistocene and coated with calcium carbonate. Meet at the Maturango Museum (100 E. Las Flores, Ridgecrest) at 8:00 am to carpool. Four-wheel-drive vehicles are necessary for those who want to cross the wash to visit the tufa limb casts. Poison Canyon is 11 miles east along Highway 178. Bring lunch or snacks, water, jacket, good walking shoes, hat, sunscreen, camera. Contact persons: Judy Breitenstein: 760-375-2158 [email protected] and Jane McEwan, 760-264-6206 [email protected]. March 25, Sunday - Highway clean-up. Leader: Scott Hetzler. Meet at the intersection of Highway 395 and Pine Creek Rd., west of 395, at 9.00 AM. We will try to be done by 1:00 pm. Contact person: Scott at (760) 873-8392. March 31, Saturday - Mary Dedecker Native Plant Garden Spring Cleaning. Leaders: Sue Weis, Jerry Zatorski, Katie Quinlan. March is a great time to remove exotic weeds before they drop their seeds, as well as trim anything needing it. We’ll meet at the garden at the Eastern California Museum in Independence at 9:00 AM.

  • Insights from Lowtemperature Thermochronometry Into
    TECTONICS, VOL. 32, 1602–1622, doi:10.1002/2013TC003377, 2013 Insights from low-temperature thermochronometry into transpressional deformation and crustal exhumation along the San Andreas fault in the western Transverse Ranges, California Nathan A. Niemi,1 Jamie T. Buscher,2 James A. Spotila,3 Martha A. House,4 and Shari A. Kelley 5 Received 21 May 2013; revised 21 October 2013; accepted 28 October 2013; published 20 December 2013. [1] The San Emigdio Mountains are an example of an archetypical, transpressional structural system, bounded to the south by the San Andreas strike-slip fault, and to the north by the active Wheeler Ridge thrust. Apatite (U-Th)/He and apatite and zircon fission track ages were obtained along transects across the range and from wells in and to the north of the range. Apatite (U-Th)/He ages are 4–6 Ma adjacent to the San Andreas fault, and both (U-Th)/He and fission track ages grow older with distance to the north from the San Andreas. The young ages north of the San Andreas fault contrast with early Miocene (U-Th)/He ages from Mount Pinos on the south side of the fault. Restoration of sample paleodepths in the San Emigdio Mountains using a regional unconformity at the base of the Eocene Tejon Formation indicates that the San Emigdio Mountains represent a crustal fragment that has been exhumed more than 5 km along the San Andreas fault since late Miocene time. Marked differences in the timing and rate of exhumation between the northern and southern sides of the San Andreas fault are difficult to reconcile with existing structural models of the western Transverse Ranges as a thin-skinned thrust system.
