Downtown Washington Street Bridge Replacement Project
Washington Street is an important thoroughfare through downtown Naperville. It is the only north‐south route in the City that crosses both the BNSF railway tracks and the West Branch of the DuPage River. Being such a vital corridor, Washington Street sees a considerable amount of traffic. In addition to vehicular traffic, Washington Street is host to a variety of small businesses and recreational areas including Fredenhagen Park and the Naperville Riverwalk.
At the center of downtown Naperville is the Washington Street bridge. Tens of thousands of vehicles traverse this bridge every single day. The structure, which is located between Aurora Avenue and Chicago Avenue, is more than 40 years old and it is in need of replacement due to its deteriorated condition. To extend its life span, the bridge has been load posted to restrict the size of vehicle that can use the bridge. The bridge is still adequate for passenger vehicles.
The purpose of this project is to replace the Washington Street bridge. Replacing the structure provides an opportunity to look at several components of the bridge and surrounding area, including the roadway segments that approach the bridge. Washington Street from Aurora Avenue to Chicago Avenue will be studied to determine the best future configuration of the area.
- Open House
The first public open house was held on February 9. The presentation boards used at this event are posted here in PDF format.
A summary of comments made by the public at this open house is available here.
- Next Steps
A second public meeting is tentatively scheduled for May 2017. This open house will present a comprehensive look at preliminary design plans for the Downtown Washington Street Bridge.
In the coming weeks, conceptual design elements to be included in the final design of the bridge will be posted to this webpage.
- Frequently Asked Questions
Why is the bridge being replaced?
The bridge foundation was constructed in 1928, widened in the 1970s and renovated in 2004. The bridge components have reached the end of their effective service life. The bridge has a special weight load limit of 15 tons which prohibits use of the bridge by nearly all trucks. Replacing the bridge also provides the opportunity to improve the existing roadway geometrics, the functionality of the Riverwalk and overall aesthetics.
Is the existing bridge safe to use now?
Yes, the existing bridge is inspected regularly to confirm public safety. However, there is a 15-ton weight limit posted for this bridge in order to reduce damage from heavy loads like trucks.
How will the community be involved?
Input from the community is very important to make this project successful. The City hosted the first public meeting for this project on February 9, 2017. The meeting was well attended and very useful input was provided by public comments. The city will host a second public meeting in May or June to highlight the proposed bridge design. As the project moves forward toward construction additional meetings with stakeholders will also occur to assure that communication and coordination is at a high level. The city will continually update the project information on this page. We will also send out project updates via press releases, social media and electronic newsletter, which you can sign up to receive on the project webpage.
When will construction begin? How will traffic be impacted by construction activities?
The construction is expected to begin in 2019. There are two basic alternatives to maintain traffic flow during construction that are currently under evaluation. One is to maintain a single lane in each direction. The other option is to close the bridge completely and thus reduce the overall construction time. In either alternative, traffic use will be reduced. Nearby bridges like Main Street and Eagle Street will enable access to the downtown from the south. Through traffic on Washington Street will need to allow for greater travel time or use alternate routes. The project will include a traffic management plan to communicate and optimize travel options.
Will business access near the bridge be affected?
Access to businesses around the construction zone and within the downtown is a priority. Work activities will be staged to maintain the ability to travel to and from businesses throughout the project.
Will the Riverwalk be improved as part of this project?
As part of this project, the current Riverwalk sidewalk under the bridge will be elevated to reduce the frequent flooding that occurs. Other improvements associated with the bridge will further enhance the Riverwalk by providing a more park-like riverscape, improving visual aesthetics, lighting and pedestrian mobility. Separate plans by North Central College at 430 S. Washington Street will connect the existing covered footbridge at Fredenhagen Park to the Riverwalk west of the Washington Street Bridge.
What will the bridge look like when completed?
Complementing the traffic and pedestrian mobility improvements the bridge will provide, the City intends to make the bridge safer and more visually paired with the beauty of adjacent parks and downtown architecture. This will include bridge improvements to provide sidewalks wide enough to carry two-way travel, barrier wall separation from traffic, architectural style and streetscape features like decorative lighting and landscaping. All of these improvements will be consistent with the new downtown streetscape standards and be similar in function to the Main Street and Eagle Street bridges.
What’s the estimated cost of the project and how is it being funded?
The preliminary estimated construction cost to replace the downtown Washington Street Bridge and complete the adjacent roadway work is $8 million. The City has secured federal funding, which will cover 80 percent of the cost.
Will there be any property acquisition required?
Traffic studies have been performed to identify ways to reduce crashes and traffic congestion and travel delays. The preferred solution involves widening the bridge to five lanes which improves the left turn lanes at Chicago Avenue and Aurora Avenue and also includes the addition of right turn lanes at the intersection of Aurora Avenue and Washington Street. To accomplish these improvements, additional right-of-way on the east and west side of Washington Street from the bridge to Aurora Avenue and on the east side of Washington Street from Chicago Avenue to the bridge is required. The additional right-of-way is necessary to relocate the sidewalks making room for the additional turn lanes. Property owners will be compensated for land which is acquired.
Will any utility work be done as part of the project?|
River crossings are very vital to utilities like water, sewage, electric, communication and natural gas. All these utilities will be included in the planning for this project. It is anticipated that most utilities will be improved during this project. Each utility provider will work with their customers as part of the project.
