  • One lane in each direction will be provided whenever possible during working hours and when work is not taking place.
  • Occasional night and weekend work is expected.
  • Speed limit reductions are anticipated and fines are double within work zone. 
  • The project is weather-dependent and the schedule is subject to change.

Project Overview

Plans to improve the intersection have been in development since 2013. This $7-million project is funded through the City’s Capital Improvement Project Fund. Planned intersection enhancements will improve the safety and functionality of the intersection. This project will raise the profile of the roadway to improve drainage, upgrade the traffic signal and provide additional capacity through the intersection. The  new intersection layout has been designed to accommodate future traffic volumes. Two lanes in each direction will be provided through the intersection and Indiana Street will be widened to accommodate double left-turn lanes in both directions. Other project improvements include:

  • New sidewalks and on-street bike lanes
  • Undergrounding utilities
  • Water line replacement
  • Storm sewer upgrades
  • Bridge expansion on 72nd Avenue over Croke Canal
