Indiana is the home to four major interstates. Two of those share a route across northern Indiana mainly due to geography. (Let’s face it, Lake Michigan is one of those things that is kind of hard to miss.) The other two connect Indianapolis to St. Louis, Chicago, Louisville, and Columbus, Ohio. Today, I want to focus on little newspaper items that I found concerning the main east-west route labelled as Interstate 70.
The plan in Indiana, as approved by the Federal Bureau of Public Roads, had I-70 being a parallel route to US 40. This would be the case through most of the eastern United States.
According to Indiana state law at the time, the Indiana State Highway Commission was required to publish annually its construction plans for the following two years. While most of the projects would be built, some were placeholders and pipe dreams that still, even to this day, never seemed to appear on any official maps. It should be noted that the plans run from 1 July to 1 July, and are subject to change along the way. And, any project after the ending 1 July (in this case 1965) would be on the following two year plan (in this case, 1965-1967).
In the post “State Highway Department Construction Plans for 1963-1965,” I mentioned I-69 and I-74. One interstate highway left off the original two year plan was I-70. The Jasper Herald of 14 November 1961 mentioned that “there was no Interstate 70 construction in the program.” State Highway Commission Chairman David Cohen mentioned that “the problem is, the route is not approved.” However, engineering work on the route would be conducted during that two year plan. 108 miles of I-70 in all the counties that it would be built would be part of the preliminary engineering projects for the 1963-1965 plan.
One of the projects that came to be with the building of I-70 was a replacement for SR 1. The Highway Commission decided to move SR 1 two miles to the east. At the time, SR 1 entered Cambridge City using Boyd Road and Center Street. It left Cambridge City on Dale Avenue at the west end of the town. The state’s new plan was to move SR 1 due north from Milton, removing the road from Boyd Road and Center Street.
The National Road Traveler (Cambridge City) of 10 June 1965 reported that the ISHC would open bids for paving of the newly constructed Interstate 70 from New Lisbon to its end, at the time, east of Cambridge City. The newspaper reported lamented that an oft used county road would be dead ended at the new interstate highway. Cambridge Road, which leaves Cambridge City as Lincoln Drive, would not have a bridge over the highway. This decision was made by the federal Bureau of Public Roads. What would become Old SR 1 and the New SR 1 would cross I-70. But Cambridge Road, being a mile between each, would not. “A bridge for East Cambridge Road would be the third span in the two-mile stretch between new and old Indiana 1 and would be a waste of funds.”
The Muncie Star Press reported on 28 April 1965 that a contract had been let to Rieth-Riley Construction Company for $2,920,987.69 to build the interstate from south of Mohawk east to 1/2 mile west of SR 209. This included three bridges: SR 13 northwest of Greenfield, SR 9 north of Greenfield, and Brandywine Creek northeast of Greenfield. The traffic disaster that would occur near the Hancock County seat was covered 20 April 2019 in an article “I-70 in Greenfield.”
The 1965-1967 two year plan, according to the Muncie Star Press of 18 October 1962, included a grand total of 21.4 miles of Interstate 70 construction. This only included sections in Henry County, and entering Wayne County. But it involved not only building the road, but also constructing 25 bridges in that section.
The 1971-1973 plan, as reported on 26 June 1971 in the Richmond Palladium-Item, included 5.8 miles of Interstate 70 in Marion County: Belmont Avenue to River Avenue (0.9 mile); south leg of the inner belt (1.5 miles); and from what is now called the North Split to Emerson Avenue (3.4 miles).
