This appendix contains the following supporting documentation on visual resources in the North Coast
Corridor (NCC):
Photo Documentation: Current photographs of various locations along the Interstate 5 (I-5) highway corridor. Table B-1 lists the view locations and the number of photographs that appear for
each. Figures B-1A through B-1G are key maps illustrating the locations of
each view. The photographs themselves appear on the gallery after the maps, and are lettered sequentially
based on their view number (e.g. Figure SD-01A, Figure SD-01B, etc.).
Proposed Locations of Intermediate Access Points (IAPs), Overhead Signs and Scanners: At the start of the gallery, Figures B-2A through B-2I are maps of proposed locations for Express
Lane IAPs, overhead signs and overhead scanners.
IAP Signage Criteria: The final section of this appendix contains
descriptions, schematics and photos of proposed design features for corridor signs at IAP
locations.

1. Placement of HOV/Managed Lanes advance warning signs as outlined Chapter 2G of the 2012
California Manual on Uniform Traffic Control Devices (CA MUTCD).
Minimum advance sign placement is about 1 mile from entry point of the Intermediate Access Points (IAPs) with advance signs to IAP entrance placed in 0.5 mile increments. Tolling signs are placed (at minimum) about 0.25 mile and 0.65 mile from the IAP entrance, respectively. Sign dimensions are summarized in Table 2G-1. Note that the figure below show only regulatory (guide) signs as they apply to IAPs.
Figure 2G-24
- Example of Signing for the Intermediate Entry to, Egress from, and End of Access-Restricted Priced Managed Lanes. Figure 2G-17 – Regulatory Signs for Managed Lanes
- Notes:
The ETC pictograph shown is an example only. The pictograph for the toll facility's adopted ETC system shall be used.
Changeable message sign elements shall be used for the numerals displayed for the variable tolls.
Figure 2G-18 – Examples of Guide Signs for Entrances to Priced Managed Lanes
- Notes:
The ETC pictographs shown are examples only. The pictograph for the toll facility's adopted ETC system shall be used.
The examples shown are for facilities on which registration in a toll account program is required for toll payments.
2. Minimum Sign and Plaque sizes.
Dimensions of signing outlined on Figure 2G-17 and Figure 2G-24 above are shown on Table 2G-1 with the appropriate signs and highway facility type marked *. See
Figure 2G-24 for sign designations. Dimensions are in inches.
Table 2G-1 – Managed and Preferential Lanes Sign and Plaque Minimum Sizes
Notes:
1. Larger signs may be used when appropriate.
2.
Dimensions in inches are shown as width x height.

3. Overhead signs.
Caltrans Standard Plans S30 show typical placement and minimum clearance from freeway pavement. Signs and sign structures require a minimum vertical clearance of 18 feet from freeway high point and edge of shoulder, respectively. Tubular overhead signs can be specified as slanted or vertical post.
2010 Standard Plan S30
- Overhead Signs-Tubular Instructions and Examples.
4. Overhead Sign- Single Post Type.
Span (cantilever) range from 20 feet to 38 feet. Height to centerline of mast arm(H) ranges from 21 feet to 29 feet relative to the bottom of base plate and is a function of the sign panel depth(D). Sign panel depth range from 50 inches to 120 inches. H and D in turn would be used to determine the post type and thickness. Please see Standard Plan S31 below for additional details.
2010 Standard Plan S31 - Overhead Signs-Tubular Single Post Type Layout and Pipe Selection. 5A Photo
- Single post type tubular overhead sign along CA 241. 5B Photo - Single post type tubular overhead sign along I-15 in Utah.
6. Overhead Sign- Two Post Type.
Spans range from 50 feet to 145 feet. Height to centerline of
mast arm(H) ranges from 21 feet to 29 feet relative to the bottom of base plate and is a function of
the sign panel depth(D). Sign panel depth range from 50 inches to 120 inches. H and D in turn
would be used to determine the post type and thickness. Please see Standard Plan S32 below for
additional details.
2010 Standard Plan S32 - Overhead Signs-Tubular Two Post Type Layout and Pipe Selection. 7. Photo – Two post type tubular overhead sign along I-15 freeway
- This sign structure includes overhead
scanners, tolling sign, CMS along with the corresponding exit sign. The lane configuration shown in this
photo is similar to the proposed lane configuration for the I-5 North Coast Corridor Project.
8. Plan showing details and dimensions for the same sign structure shown on the photo above.
Phase 4 Plan - Overhead Sign Structures Sign Details.
9. Overhead Sign Truss - Single Post Type
Truss frame length, which is the sum of the left and right arm
lengths of the sign structure, range from a minimum 12 feet to a maximum of 60 feet. Standard Plan S4 show
details for the placement of sign panels on the sign structure (left and right sides) as well as minimum and
maximum length of the panels (0 feet and 40 feet, respectively). Table IV of Standard Plan S4 show truss frame
depth and maximum vertical spacing, L, as a function of sign panel depth (ranges from 50 inches to 120 inches).
2010 Standard Plan S4 - Overhead Signs-Truss Single Post Type Structural Frame Members Details No. 1.
10. Standard Plan S5
Outline details as to the structural connection and spacing of vertical, horizontal and diagonal elements of the truss as a function of frame length and sign panel depth.
