About Heading
I-70 was originally envisioned as the connecting route between north Washington and the PA Turnpike in Monroeville. However, the Department of Highways later designated that route as I-79 and proposed the I-70 corridor take on a new alignment that would connect the West Virginia state line to the Maryland state line. The construction of the I-70 corridor as we know it today began in 1953 connecting Bentleyville and S.R. 481. Over the following 15 years, I-70 was built section by section and fully completed by 1968.
PennDOT District 12 is responsible for the design, construction and maintenance of I-70 from the West Virginia state line east to New Stanton, PA (exit 57). This stretch of I-70 connects with three other Pennsylvania Interstate routes: I-79, I-43 (PA Turnpike Extension) and I-76 (PA Turnpike Mainline) and West Virginia's I-70. Some of the other popular connecting State Routes (SR) include: SR 481, SR 31, SR 119, SR 51, SR 519, SR 19, SR 18, and SR 40. Travelers can utilize I-70 to reach destinations such as, Wheeling, West Virginia; Washington, PA, and Pittsburgh, PA.
Some roadway and bridge sections of I-70 in southwestern PA were constructed more than 55 years ago. As a result, PennDOT is frequently monitoring the conditions of the Interstate to identify priority rehabilitation and reconstruction needs to improve safety and better accomodate today's motor vehicles. As funding is available, PennDOT's goal is to address the following:
- Replace or rehabilitate existing
deteriorating bridges
- Upgrade existing interchange
acceleration and deceleration
- Improve the roadway geometry
- Replace bridges with less than
16'6" underclearance
- Improve interchange traffic flow
