Drivers are now motoring across a new bridge in northern Kane County. The Longmeadow Parkway Bridge Corridor opened to the public on August 29, 2024.
The cornerstone of the $200 million project is a new bridge that provides an additional route over the Fox River. The entire corridor stretches 5.6 miles, from Huntley Road to Route 62, and includes a bike and pedestrian path connecting to the Fox River Trail.
The opening was celebrated with a ribbon-cutting event attended by over 175 people including Governor JB Pritzker, Kane County elected officials, members of the Kane County Division of Transportation, state lawmakers, and local leaders.
Originally, Kane County planned to fund the bridge construction with tolls. However, over the past two years, the County successfully secured an additional $30 million in state funding to cover the costs. As a result, the bridge was completed without imposing tolls.

​The Kane County Board recently approved the 2024-2028 Transportation Improvement Program, known as the TIP. The TIP contains the 5-year capital plan for the Division of Transportation. It provides information to the public on the expected revenues and expenditures and the projects planned for implementation during the 5-year timeframe. Click on this link to view the approved plan. 

We are pleased to announce the publication of our new interactive web app that allows users to view the projects in greater detail. The user can view by project category, location, County Board District, and more. ​

Why does KDOT typically put taller vegetation blocking visibility through the central island of their roundabouts?

 

Thought and planning goes into the native landscaping found in the central islands of our roundabouts. While there is nothing fundamentally wrong with seeing the upstream approach of cars from a long ways off and timing your own approach accordingly, the real value in sight distance restrictions provided by taller vegetation in the roundabout is the positive effect they have on those vehicles getting ready to enter the roundabout.

 

As vehicles are getting ready to enter the roundabout, restricting sight distance across the central island with strategic taller landscaping may enhance the safety of the intersection by encouraging lower speeds and making only the left-hand side of the roundabout the focal point. In addition to the increased aesthetic value, a well-landscaped island will make both circulating and entering vehicles more cautious by limiting how far ahead they can see. A circulating vehicle likely will be a bit slower around the curve if its view ahead is restricted (see graphics below). That makes it easier for a car entering the circulating lane to receive a reasonable gap. If sight distance restrictions can limit circulating vehicles to 20 mph, you need less than 120 feet of pavement to provide a four-second entry gap – which is big enough for just about any passenger car.

 

An additional characteristic of taller central island landscaping is that it shields the headlights of oncoming vehicles making it easier to see the circulating lane as a driver approaches a roundabout.​Graphic of Roundabout sight distances.
