| Guanella Pass Road is located within the Pike and Arapaho National    |
| Forests, and Park and Clear Creek Counties, beginning at U.S. 285 in  |
| Grant and proceeding in a northerly direction over Guanella Pass to   |
| Georgetown. The overall project is approximately 38.2 kilometers      |
| (23.7 miles) long.                                                    |
|                                                                       |
| The first phase of the overall project \[CO PFH 80-1(1) & 2(2)\] is   |
| located on the center portion of the overall corridor, and involved   |
| the rehabilitation or reconstruction of approximately 14.2 kilometers |
| (8.8 miles) of roadway. Included were retaining walls, parking areas, |
| guardrail, improved drainage structures and varied surfacing. This    |
| first phase is scheduled for completion in 2007.                      |
|                                                                       |
| The remaining portions involve the rehabilitation or reconstruction   |
| of approximately 24.0 kilometers (14.9 miles) of roadway with         |
| additional retaining walls, parking areas, guardrail, improved        |
| drainage structures and varied surfacing. The approximate stations of |
| the Phase 2 project are from 1+000 through 16+000 (Segment 1) and     |
| from 30+240 through 39+200 (Segment 2). Also included in the project  |
| are minor improvements within the Town of Georgetown starting from    |
| the end of the main project and progressing along the haul route to   |
| the intersection of Argentine Street and 15^th^ Street.               |

| The Central Federal Lands Highway Division (CFLHD) of the Federal     |
| Highway Administration (FHWA), in cooperation with the U.S.D.A Forest |
| Service (USFS) in the Tonto National Forest (TNF), and Gila County,   |
| Arizona are proposing to reconstruct (4R) a portion of roadway within |
| the Tonto National Forest. The reconstruction work is a continuation  |
| of the previous Forest Highway 512 project and consists of            |
| approximately 9.957 km of road reconstruction, drainage improvements, |
| and grading.                                                          |

| The Central Federal Lands Highway Division (CFLHD) of the Federal     |
| Highway Administration (FHWA), in cooperation with the United States  |
| Forest Service (USFS) is proposing to reconstruct approximately 6.13  |
| kilometers (3.81 miles) of Trinity County Route 114 from              |
| approximately milepost 10.4 to milepost 14.3. The project             |
| reconstruction entails repaving, widening, modifying alignment,       |
| grading and drainage for the CA FH /County Road 114, Hyampom Road.    |
|                                                                       |
| Hyampom Road/County Route 114 is classified as a major rural          |
| collector highway. The county route is broken into 6 segments. The    |
| proposed construction for this project encompasses the entire length  |
| of segment 5. Segment 5 is an existing single lane section proposed   |
| to be widened to two full lanes to be contiguous with the rest of the |
| route                                                                 |

| The Central Federal Lands Highway Division (CFLHD) of the Federal     |
| Highway Administration (FHWA), in cooperation with the National Park  |
| Service (NPS) is proposing to rehabilitate the pavement and drainage  |
| conditions for CO PRA MEVE 10(8) & 200(1), Chapin Mesa and Wetherill  |
| Mesa Roads. This project will consist of the rehabilitation,          |
| restoration, and resurfacing (3R) of approximately 9.50 miles of      |
| Route 10 from Park Point Overlook to the Park Headquarters Loop       |
| Intersection. This project will also include the temporary pavement   |
| preservation of approximately 12.33 miles of Route 200, beginning at  |
| Route 10, and continuing to the Wetherill Mesa parking area. Also     |
| included are the rehabilitation of guardrail, curb and various        |
| drainage structures.                                                  |
|                                                                       |
| The Chapin Mesa and Wetherill Mesa Roads project is located about 11  |
| miles east of the City of Cortez, Colorado on US 160. The proposed    |
| project is in rolling and mountainous terrain. Elevation is           |
| approximately 8000 ft. The routes are wholly within Mesa Verde        |
| National Park.                                                        |
|                                                                       |
| These projects were originally scoped in 2002 as part of a much       |
| larger project to rehabilitate most of the paved roads at Mesa Verde  |
| National Park. The larger project was delayed and national funding    |
| constraints necessitated the larger project be broken back out into   |
| smaller projects. This project is a result of that repackaging.       |
|                                                                       |
| Due to funding constraints, this project will be further divided into |
| three schedules. Schedule A will consist of spot overlays and         |
| patching on Chapin Mesa Road between the park entrance and Park Point |
| Overlook, all the improvements to Wetherill Mesa Road, and the Chapin |
| Mesa Road improvements from just South of the intersection with       |
| Wetherill Mesa Road to the Park Headquarters Loop Intersection.       |
| Schedule B will consist of all the improvements in Schedule A plus    |
| some more spot overlays and patching on Chapin Mesa Road between the  |
| park entrance and Park Point Overlook. In addition, Schedule B will   |
| consist of spot repairs on Chapin Mesa Road between Park Point        |
| Overlook and Far View. The intent of these spot repairs is to repair  |
| exceptionally poor isolated pavement areas on Chapin Mesa Road.       |
| Schedule C will consist of the project in its entirety, without the   |
| spot repairs on Chapin Mesa Road.                                     |

| The Central Federal Lands Highway Division (CFLHD) of the Federal     |
| Highway Administration (FHWA), in cooperation with Inyo National      |
| Forest (INF), and the Town of Mammoth Lakes (Town) is proposing to    |
| improve the pavement and drainage conditions for Lake Mary Road in    |
| the INF. The project, CA PFH 81-1(1), consists of the rehabilitation, |
| restoration, and resurfacing (3R) of 2.6 miles of this route between  |
| the Horseshoe Lake Parking Area (MP 4.9) and the Twin Lakes Loop Road |
| (04S22) (MP 2.3) in Mammoth Lakes, California. Mammoth Lakes is       |
| located in Mono County on SR 203, approximately 168 miles south of    |
| Reno, Nevada along US 395.                                            |

| The Central Federal Lands Highway Division (CFLHD) of the Federal     |
| Highway Administration (FHWA), in cooperation with the National Park  |
| Service (NPS) is proposing to rehabilitate the pavement and drainage  |
| conditions for UT PRA DINO 10(2) & 100(1) Cub Creek (Route 10) and    |
| Quarry Access Roads (Route 100). This project will consist of the     |
| rehabilitation, restoration, and resurfacing (3R) of approximately    |
| 9.4 miles of Route 10 near the Dinosaurs National Monument Entrance   |
| at the end of State Highway 149, north of Jenson UT. This project     |
| will also include approximately 0.6 miles of Route 100, beginning at  |
| Route 10, heading northerly. Also included are rehabilitation of two  |
| Quarry parking lots, guardrail and various drainage structures.       |
|                                                                       |
| The Cub Creek Road and Quarry Access Roads project is located about   |
| 11 miles east of Vernal, UT and 25 miles west of the CO state line.   |
| The proposed project is in dissected plateau country with rolling     |
| terrain. Elevation is approximately 5100 ft. The routes are wholly    |
| within the Dinosaur National Monument.                                |
