Post Forest Drive from West Ox Road to Random Hills Road

The sidewalk along the south side of Post Forest Drive will be upgraded to a ten-foot-wide shared-use path from just west of Black Ironwood Drive to Random Hills Road. 

In order to accommodate the ten-foot-wide shared-use path, Post Forest Drive will be restriped without bicycle lanes, curb and gutter will be modified as needed, and the bus shelter on eastbound Post Forest Drive just past Black Ironwood Drive will be moved or replaced. Post Forest Drive east of Random Hills Road will be restriped to align with the new road configuration.

Improvements at West Ox Road and Post Forest Drive include:

  • Adding crosswalks along the north and west sides of the intersection
  • Enhancing Americans with Disabilities Act (ADA) curb ramps

Random Hills Road from Post Forest Drive to Monument Drive

The existing sidewalk along the east side of Random Hills Road will be upgraded to a ten-foot-wide shared-use path from Post Forest Drive to the existing shared-use path just beyond the Monument Drive overpass.

Improvements at Post Forest Drive and Random Hills Road include:

  • Adding a crosswalk along the north side of the intersection
  • Enhancing ADA curb ramps
