The Building of I-465

The building of the Indianapolis bypass, Interstate 465, involved a lot of pieces to fall together. Property acquisition was a big part of that. Then came the money involved in building the interstate in the first place.

The Indianapolis News, on 14 December 1959, published the above photograph showing the first section of Interstate 465 to be built. It was already under construction when the article was published. Two contracts, on for the 46th Street overpass ($149,968.03) and the 56th Street overpass ($168,178.51) had already been signed. It is mentioned in the caption that “design work hasn’t been completed on the Interstate 64-465 cloverleaf interchange, although a $582,836.95 bid has been received for part of the work.” One wonders where that cloverleaf might have been.

Even before that, it was announced in the Indianapolis News of 30 April 1959 that the contract had been let for the grade separation (bridge) for 34th Street over the new interstate. What is of particular note is the line “over west leg of new Ind. 100, to be renumbered Interstate 465.”

Late 1962 would be the planned bidding date for a contract to build a new interchange in the already completed northwest leg of I-465. At the time, 38th Street was being extended and improved across northwestern Marion County. It was decided by the Highway Commission to create a diamond interchange where 38th Street crossed over I-465. At the time, there were no interchanges on the northwest side between I-74/US 136 and I-65.

The end of November, 1962, saw the announcement of a $3,197,216.11 contract to build the interstate from Meridian Street to Carson Avenue on the south side of Marion County. This contract was let on the same day they were opened. This was to allow for quicker construction of the bypass. Also, this was to give the contractor as much time as possible to complete construction before the deadline on December 1963. The 2.3 miles of new road and five bridges involved in this section of interstate would bring the highway to almost the pending interchange at I-65.

Another contract had to be let in this section when it was realized that the banks of Lick Creek, with the interstate built on both sides near Carson Avenue, had to be reinforced. To the tune of $298,014.40. The creek, as of 21 April 1964, had eroded its bank the previous winter requiring the building of additional slope walls and revetments to keep the creek where it belonged between the two directions of I-465.

In 1963, a contract bid to build the large interchange on the south side of Marion County between I-65 and I-465 was one of the bigger contracts. The project involved eight bridges and two miles of pavement to connect two of the sections that were already under construction or completed. The low bid on that particular contract was $3,507,672.18 by McMahan Construction Company of Rochester and R. L. Schutt Construction Company of Indianapolis. This bid was announced publicly on 20 April 1963.

The first contract to be opened up after the Fall 1964 completion of I-465 between I-74 and SR 100 (Shadeland Avenue) was the bidding, starting 25 May 1965, of a single bridge over US 52 (Brookville Road) and the Baltimore & Ohio railroad tracks on the southeast side of the county. This contract, and the rest of them connecting I-74 to US 40 on the east side had been on hold due to right-of-way difficulties. Norman F. Schafer, executive director of the State Highway Commission, commented that the summer of 1965 would be the first time in more than four years that no major construction was underway on the beltway.

Indianapolis News, 24 August 1967. Construction underway on the north leg…and a proposed SR 100 connecting the west leg at I-65 to the north leg west of Zionsville Road. This section would be built as SR 100, but like the rest of the route, would become part of I-465, causing confusion for over two decades with the “dog leg.”

The north and northeast legs of I-465 would be the hardest to complete. So much so that in July 1968, the Noblesville Ledger ran photos of the construction of the interstate through the small section of Hamilton County through which it passes. It is mentioned that the “State Highway Department schedules call for ‘phasing out’ I-465 construction from it western link with I-65 east to White River by the first winter freeze. However, I-164 from just north of Fall Creek northwest to White River will not start this year.” I would share the photos from that newspaper, but they are very dark and hard to see.

Indianapolis News, 17 March 1960. Proposed new route for the north leg of I-465 through Boone and Hamilton Counties.

I would be remiss if I didn’t mention one “might have been” on this entry. I found this map of another proposal for the north leg of the bypass. On 30 Janaury 2020, I wrote “Alternate Routes for I-465 on North Side of Indianapolis,” but didn’t find this map. I thought it appropriate to share it here.
