MKA used five full-time survey crews working with four contractors during the construction of this pipeline gathering system consisting of MKA survey crews were directly responsible for locating, tracking and chaining all of the pipe and materials used in the mainline portion of this pipeline system, excluding valve sites fabricated off site. Attributes The project involved environmentally sensitive areas that required detailed topographic surveys of four steep stream crossings. Site plans depicted the disturbances and helped facilitate the design of a stabilization plan for the steep slopes on each side of the sensitive stream crossings.

At first, Chief Engineer Samuel W. Marshall supervised engineers, but within three months that number grew to more than 1, The added staff was necessary for the Commission to meet the construction-season cycle and the deadline for completion set by the federal government.

Commission officials meet on October 10, From left to right: Commission nominee Edward N. The engineers also had to change they way they designed highways. Highways had always been built with flat curves to discourage speeding.

Now, the engineers were expected to design easy grades, to allow cars and trucks year round use. Long, sweeping curves would give ample room for high speeds and safe stopping distances.

The engineers decided on the following standards: A right-of-way width of feet. A four-lane divided configuration, with foot-wide concrete traffic lanes, a ten-foot-wide median strip and ten-foot-wide shoulders, for a total of 78 foot width of ROW.

Early plans called for ten-foot-wide lanes, and just a four-foot-wide median strip. Also, a cheaper design that used two concrete lanes and two asphalt lanes was dropped.

Substantial superelevation, or banking, on curves. Limited access, with 1,foot-long entrance and exit ramps to provide plenty of distance for accelerating and decelerating. A minimum foot sight distance from motorist to traffic ahead. No cross streets, driveways, traffic signals, crosswalks or railroad grade crossings.

All vehicular or pedestrian traffic would go over or under the Turnpike. Along the same distance on the Lincoln Highway and US 11, there were cross streets, 12 railroad crossings and 25 traffic signals. What separated this highway from others was that it was considered one continuous design task from Irwin to Carlisle.

Charles Noble, a design engineer for the Commission who later moved on to become chief engineer for the New Jersey Highway Department and the New Jersey Turnpike Authority, described this feat in the July Civil Engineering magazine, "Unlike the existing highway systems of the United States, in which design standards fluctuate every few miles, depending on the date of construction, the Turnpike will have the same design characteristics throughout its mile length.

Every effort has been directed towards securing uniform and consistent operating conditions for the motorist. Sixteen million visitors took a 16 minute narrated ride through a vision of the United States in the far off year of Norman Bel Geddes, an industrial designer, built a diorama that had as its focus limited-access superhighways.

People were able to get a taste of the things to come. However, many of the principles that were showcased in the exhibit, and used in the Turnpike's design, were already a part of Germany's Autobahns and on a mile section of the Bronx River Parkway in New York City. As the proposed completion date drew near, there was one problem the state was facing: This doesn't mean that no work had taken place; however, workers had been busying pumping water from the abandoned South Pennsylvania Railroad tunnels so that engineers could determine their condition.

That changed when the Commission awarded Contract Number 1 to the L. After this happened, the PTC began doing business with owners of properties that lay in the path of the Turnpike.Drivers can expect to see construction work on many state-owned roads and bridges throughout western Pennsylvania this year.
