Creation: I-70's origins go back to at least the 1943 Interregional Highway System Proposal. It was not on the 1939 proposed system.
Oddly, there is evidence West Virginia believed this routing was supposed to be I-70S when the numbering of interstates was initially rolled out.
Adjustments: The first portion of I-70 to be completed was the Fort Henry Bridge to WV 2 interchange, which opened in 1955, though it is unclear when I-70 was actually signed on this short stretch of freeway.
By 1963, I-70 was open from today's Exit 1B to Exit 4.
In 1967, the Wheeling Tunnel was completed. Early maps submitted to AASHO suggested I-70 was going to go around Wheeling Hill the same way US 40 does, but per a summary of the tunnel's history, WVDOH had already decided to build a tunnel by the time the interstate system was off the ground.
In 1968, I-70 was opened across the Ohio River
In 1971, the remainder of I-70 to Pennsylvania was completed.
Improvements: Opened as 4 lanes everywhere except Exits 2A and 5 which is 6-lanes.
The Wheeling Tunnel was rehabbed in the late 2000s.
New Interchanges: Exit 10 - CR 65 (between 2004-07)
Comment: While I-70 is 4-laned through the tunnel, only the left lane in each direction is a through lane - the right lane forces onto exit ramps immediately exiting the tunnel.
