(Richmond, IN)--The Richmond Police Department is preparing for what could be a big traffic headache starting soon. RPD met with INDOT officials to discuss what will happen between September 8th and 22nd. That’s when westbound I-70 will be diverted to one lane to allow for work on the New Paris Pike overpass. RPD says big backups will likely occur on 70 that will cause drivers to divert onto U.S. 40 into Richmond. Those drivers will then head north on Chester Boulevard, which is also undergoing major construction.
