The story of the Boy Scout Ramps on Interstate 79 North in NW Pennsylvania

If you are traveling on Interstate 79 North of Pittsburgh, you may notice the remnants of a set of off and on ramps at mile 100 just north of Exit 99 (US 422).  There's a story behind these ramps.  Forty years ago, these ramps were built specifically for two Boy Scout Jamboree's that were held at Moraine State Park - 1973 and 1977.  The ramps purpose were to provide access to the north shore of Lake Arthur where the bulk of the festivities and campsite for the Jamboree were located.  (Lawrence County Memories has a great write up and map of the festivities on its site.)

Not long after the Jamboree ended the ramps were abandoned.  There are still remnants of the Boy Scout Ramps today.

The google street view image above gives a view along West Park Road of where the set of ramps intersected the highway.  The ramps provided direct access to North Shore Drive (which is the right turn from here.)

The benefit of these ramps were to handle the overflow of scouts and other visitors to Moraine State Park during the 1973 and 1977 Jamborees.  Moraine State Park was the eastern jamboree site in 1973 and hosted the entire Jamboree in 1977.  Over 28,000 scouts attended the 1977 jamboree.  So the need to handle the additional traffic is why the ramps were built.  This was due to the lack of direct access to the North Shore of the park from Interstate 79.  The nearby Exit 99 for US 422 is the closest to the park and provides direct access to the South Shore.  However, because of the configuration of the ramps and park service roads, direct access from I-79 or US 422 East was not possible.  The only direct access to the North Shore is via ramps from US 422 West. (See google map below)  The best access to the North Shore of Moraine State Park is via PA 488 three miles to the South via Exit 96.



Fortunately, there has been new developments in providing direct access to the North Shore of Moraine State Park from Interstate 79 and US 422 West.  In July 2017, construction began on a 15 month project that will build new ramps along US 422 East and Westbound to allow for direct access to the North Shore of the park via West Park Road.  The new US 422 interchange will allow I-79 traffic to use Exit 99 as the gateway for direct access to all points within Moraine State Park.This project will also include improvements to the Interstate 79/US 422 interchange (Exit 99).  The cost of the project is $4.5 million.

Mineral King Road, the White Chief Mine, and the unbuilt California State Route 276

Back in July of 2016 I took Mineral King Road east from California State Route 198 to Mineral King Valley within the Sierra Nevada Mountains of Sequoia National Park.  This June I revisited Mineral King Valley and made my way up to the White Chief Mine.


Mineral King Road is a 24.8 mile rural highway maintained by the National Park Service and as Tulare County Mountain Road 375.  Mineral King Road originates at California State Route 198 in Three Rivers near the confluence of the Middle Fork Kaweah River and the East Fork Kaweah River.  Mineral King Road climbs from a starting elevation of 1,400 feet above sea level to 7,830 feet above sea level at the White Chief Mine Trailhead in Mineral King Valley.  Notably Mineral King Road is stated to have 697 curves.


Mineral King Road has an average grade of 5.1% but has several stretches between 15-20% in places.  Pjammycycling has a detailed breakdown on the grade levels over the entirety of Mineral King Road.

Hetch Hetchy Valley; Hetch Hetchy Railroad, abandoned Lake Eleanor Road, and the Wapama Fall Bridge

This June I took a trip out to Yosemite National Park upon receiving my COVID-19 Day Use Reservation.  My destination in Yosemite National Park was out in Hetch Hetchy Valley.  I sought to hike to the Wapama Fall Bridge which took me through some of the path of the former Hetch Hetchy Valley Railroad and abandoned Lake Eleanor Road.



Part 1; Hetch Hetchy Valley, the Hetch Hetchy Railroad, and reservoir roads

Hetch Hetchy is glacially carved valley similar to Yosemite Valley which is located on the Tuolumne River of Tuolumne County.  Hetch Hetchy Valley presently is impounded by the O'Shaughnessy Dam which was completed during 1923 as part of a project to deliver water and hydroelectric power to the City of San Francisco.  Before being impounded Hetch Hetchy Valley had an average depth of approximately 1,800 feet with a maximum depth of approximately 3,000 feet.  Hetch Hetchy Valley is approximately three miles long and as much as a half mile wide.  Hetch Hetchy Valley is located dow…

California's Rogue Sign State Route Shields

While recently revisiting Yosemite National Park I took a couple minutes to capture some of the California Sign State Route shields posted by the National Park Service ("NPS").  None of the NPS shields were actually posted on roadways maintained by Caltrans but were clearly intended to create route continuity with the Sign State Highways.  This phenomenon is not exclusive to Yosemite National Park and can be found on numerous roads not maintained by Caltrans throughout California.



Part 1; Route continuity over who maintains the route

In the very early era of State Highways in California the Division of Highways didn't actually field sign the Auto Trails or even US Routes.  The responsibility of Highway signage fell to the California State Automobile Association ("CSAA") and Automobile Club of Southern California ("ACSC").  The Auto Clubs simply signed Highways on roadways that best served navigational purposes.  These navigational purposes often didn&#…
