interchange access, in unincorporated Center Township. Farther northwest, US 35 has its northern terminus where it meets US 20 in Springfield Township, just east of an interchange with I-94, near Michigan City. Logansport issues Logansport area residents, the sheriff's department and at least one transportation expert have voiced concerns about the split diamond interchange used on the Logansport section of the Hoosier Heartland Highway. From the interchange's opening in October 2013 through February 28, 2016, there had been 71 two-vehicle crashes at or near the interchange, 53 of those at the interchange's four intersections, two fatalities, and a number of injuries. Possible causes for the accidents include drivers' unfamiliarity with this type of interchange, which is typically built in cities, and is not common in semi-rural small towns; drivers' mistaking the frontage roads for entrance ramps and not stopping when required; the complexity of four major traffic routes converging on one interchange; ramp/frontage traffic controlled by stop signs alone, with cross-traffic not having to stop; stop signs not clearly visible at the crest of the exit ramps. In response, the Indiana Department of Transportation (INDOT) 2014 added signage, placed flashing lights on the stop signs, and installed rumble strips. These steps reduced, but did not eliminate the problems, with one of the fatalities taking place after these fixes. INDOT was planning by spring 2016 to add overhead flashers, move the stop signs to more visible positions, install channelizing islands and increase overhead intersection lighting. History West Virginia Originally, US 35 was routed from Charleston, West Virginia, on the north side of the Kanawha River (the current WV 62) to Point Pleasant until the collapse of the Silver Bridge in 1967. When the new Silver Memorial Bridge was completed in 1969, US 35 was moved to the south side of the river (the former WV 17) away from Point Pleasant, and its southern terminus was in St. Albans, West Virginia, at the junction of US 60. Before funding was made available to convert US 35 to an expressway, a possibility had been put forward that the route would have been completed as a toll road. Prior to June 15, 2009, US 35 was relocated onto a new four-lane, mostly at-grade, expressway alignment running from I-64 in Teays Valley to a point about before the Lower Buffalo Bridge, for a length of . On that date, the old segment of US 35
