Interstate 70 at Kammerer Construction Photos

Image
By
A few weeks ago in response to my post about the early construction of Interstate 70 in Southwestern Pennsylvania, I received a handful of photos from Randy Metz of the construction of the highway at the Kammerer exit which is now Exit 31.  These photos which date from the mid-1950s show the conversion of an at-grade intersection of then Alternate PA 71 and McIlvanie Road to an interchange. 

Alternate PA 71 was known as the "Express Highway" that gave Mid-Mon Valley towns a direct link to the Pennsylvania Turnpike in New Stanton.  This highway would be added to the Interstate Highway System as Interstate 70S in 1960 and changed to Interstate 70 in 1964.  When the four-lane highway was originally built, it was built as a mix of interchanges and at-grade intersections.  These intersections were either replaced with overpasses or slowly converted to interchanges in the late 1950s.

Mr. Metz's family still resides and operates a farm nearby.  He was kind enough to share these photos that show the early history of one of Western Pennsylvania's busiest highways.

This photo shows the construction of the overpass that carries McIlvanie Road over the highway.  What is now Exit 31 on Interstate 70 is just beginning to take place.  The Carlton Motel was already in business and was served via a driveway that was at grade with the highway.  It also appears that Alternate 71 ended here temporarily.

The Carlton Motel was built by the Carl family and opened in 1953 and would expand from seven to 25 rooms by 1960. (1)

The large tree in this photo was removed to make way for what would be the offramp from westbound I-70.  That again is the Carlton Motel in the background.  After the interchange was built, the motel's driveway in the first photo was moved to the westbound offramp.  When the motel added a restaurant in 1960,  the odd driveway off the exit ramp was removed.

The color photo show some of the various dump trucks that were used in the highway's construction.  As a result of building the new highway, the Metz Family farm would be spilt in two as the state needed 26 acres of their property for the right of way.   The family did get a 7' x 7' tunnel under the highway connecting the split properties and allowing cattle and tractors to go from one side of the Interstate to the other.

This old postcard shows the Carlton Motel and Restaurant along with Interstate 70 sometime in the 1960s.  This shows how substandard the Interstate highway was 50 years ago.  The center median was a 6-inch wide x 4-inch high raised curb.  In addition, it appears that the outside shoulders were not paved.

A "turnpike" design, largely modeled after the first turnpike, the 1940 Pennsylvania, later I-76. These substandard roads, state of the art for their time, were grandfathered into the Interstate System. Worst features were the narrow median and lack of consistent shoulders, as well as abrupt on and off ramps, where stop signs were sometimes utilized.

They just razed the former Cartlon motel building about a year or so ago. Last time I was thru the restaurant is still standing but the actual restaurant has ceased operations at that site and is now located in nearby downtown Bentleyville.

Former US Route 50 and the Pioneer Route Lincoln Highway on Johnson's Pass Road

By
Johnson's Pass Road is one of the oldest highway corridors in California.  Johnson's Pass was part of the Lake Tahoe Wagon Road as it was completed during 1856 over the Sierra Nevada.  The pass would later be incorporated into the Pioneer Branch of the Lincoln Highway in 1913 and US Route 50 in 1926.  Johnson's Pass Road would be bypassed by a new alignment of US Route 50 over Echo Summit in 1938.  A replacement of the Meyers Grade east of Johnson's Pass would be opened to traffic in 1947.   Johnson's Pass Road remains accessible to traffic and is still signed by the Lincoln Highway Association.  Pictured as the blog cover is the view from the top of Johnson's Pass Road overlooking modern US Route 50 and Lake Tahoe.   Part 1; the history of Johnson's Pass Much of the history of what become the Lake Tahoe Wagon Road is discussed in the  September 1950 California Highways & Public Works  during its Centennial Edition.  The or...

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

By
The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were p...

Old NC 10 - The Central Highway: Old Fort to Black Mountain through the Royal Gorge

By
A unique way of tracing the remnants of the Central Highway is through the mountainous terrain of Eastern Buncombe and Western McDowell Counties.  From the east on US 70, you reach the base of Blue Ridge Mountains at the town of Old Fort.  Old Fort is a tiny rail town that the old Central Highway and now US 70 goes through.  The Central Highway can be followed via a right onto Mill Creek Road from US 70.  Follow the highway as it takes you closer to the mountains.  When Mill Creek Road bears right to head towards Andrews Geyser stay straight until the road ends at a gate.  The nearby Piney Grove Church can be used for parking.  At this point, the old Central Highway began a 3.5 mile climb of the mountain to Swannanoa Gap.  NC 10 and later US 70 travelers followed this road for over 30 years until a new and modern four lane US 70 was built to the south.  This same four lane road would eventually become Interstate 40.    The Centra...
