Work will include the replacement of three pairs of mainline bridges, replacement of a culvert and the installation of cable guardrail in the median, according to a letter from the Clark County-Springfield Transportation Coordinating Committee to the Dayton Development Coalition, advocating for funding in fiscal year 2016.
