When I posted about routes to get to the Indianapolis Motor Speedway, someone of Facebook had posted a comment about the direct route using Indiana Avenue and 16th Street from downtown Indianapolis. I responded that part of the problem was that 16th Street, at the time (1919) did not exist between Lafayette Road and Northwestern Avenue (now Dr. Martin Luther King Jr. Street). After crossing the White River on the Emrichsville Bridge, the streets turned either north onto White River Parkway East Drive or southeast onto what was Crawfordsville Road.
It should also be noted that the most people, at that time, thought of Crawfordsville Road (now Waterway Boulevard) as the first choice as it was the one that had been in place the longest. Indiana Avenue came long after the Crawfordsville Road, and both of those streets connected to Indiana Avenue at 10th Street across Fall Creek. The moving of the south end of Waterway Boulevard, as it is today, didn’t happen until sometime after World War II.
But west of the White River, at 16th Street, was both US 52 (Lafayette Road) and SR 34 (16th Street). The state roads followed White River West Drive to Washington Street, because the road didn’t exist east of the river. This would connect US 52 (and possibly SR 34) to US 40 under what is now the Indianapolis Zoo.
It would be shortly after the 1919 map was published that 16th Street would be built from Indiana Avenue to the Emrichsville Bridge. But that was the extent of the new 16th Street. And even then, the 16th Street that was built was north of where it should have been. 16th Street through Marion County, of most of it, is along the half section line. Since the Emrichsville Bridge was angled north as it crossed west to east, 16th Street would be connected north of the half-section line where it belonged.
Fast forward to 1933. The Indianapolis Board of Public Works decided on several projects to be completed during the 1934 construction season. Two of the projects included bridges over Fall Creek. One of those would be on 16th Street. By this time, there was a short section of 16th Street from Gent Avenue to Fall Creek and just barely west of Northwestern Avenue.
The bridge over Fall Creek would allow connection between the two sections of 16th Street. Another part of the project would be widening the road that was there. In 1934 money, the project to construct and widen 16th Street from Northwestern Avenue to the Emrichsville Bridge would cost $280,000. The new bridge over Fall Creek would cost $250,000.
A remodel of the Emrichsville Bridge would also be part of the project. The northwest wing of the bridge would be cut off and the south sidewalk to be completely removed to create a better turning angle between the sections of 16th Street on either end. The city wouldn’t have to foot the entire bill for the new construction and widening. The city was working with the Indiana State Highway Commission for federal funding (at that time, a 50/50 split) for the project as the state would most likely (and did) add that section of 16th Street to the state highway system as part of US 52 and SR 34.
Another part of this project would be the widening of West Street from 16th Street to Bluff Road. From Washington Street north West Street was SR 29. From Washington Street south, it would become SR 37. Again, the cost would be shared between the ISHC and the federal government.
The Emrichsville Bridge would last another 14 years. It was torn down in 1948 to create a wider, more direct bridge for 16th Street/US 52/SR 34 across White River. Ultimately, the new 16th Street from White River to Dr. Martin Luther King Jr. Street would look as it does in the Google map shown below. It would also remain a state road until the late 1970s, when US 136 (formerly SR 34) was removed from inside the I-465 loop. US 52 had been the first removed and rerouted along I-465 when that road was complete from the northwest side to the southeast side.
