1. Why is this project needed?
This project was identified by the City of Fishers, Hamilton County Highway Department, City of Noblesville, and INDOT to alleviate challenges such traffic congestion, to improve connectivity in our community and to proactively address future growth and additional traffic. 

A 2010 SR 37 Mobility Study also concluded that most of the intersections are currently operating at an unacceptable level of service.

2. What intersections will be improved as a part of this infrastructure project?
The infrastructure project includes the intersections of SR 37 and 126th, 131st, 135th, 141st and 146th Streets.

3. Once complete, what will SR 37 intersections from 126th to 146th Streets look like?
The improvement project will convert each cross street from a signalized intersection to a roundabout interchange with an on/off exit system. Much like the improvements made to Keystone Parkway in the City of Carmel, the SR 37 project will be a separated grade project to allow for free flowing thru traffic on SR 37 and increased traffic flow for the cross streets.

An Intersection Rendering is available and additional information will be made available for each rehabilitated intersection. 

4. The improvement projects include a separated grade with roundabout interchanges; what other alternatives were studied when evaluating this project?
The 2010 SR 37 Mobility Study evaluated the merits of a grade separation at the existing intersections and concluded that replacing traffic signals with interchanges would significantly improve safety and mobility through the corridor without the need for additional travel lanes. 

5. I travel SR 37 to and from I-69 every workday. Once complete, how will this impact my commute?
Once the SR 37 project is complete, there will no longer be signalized intersections on the corridor. Traffic is expected to flow more fluidly from north of 146th Street to I-69. In addition, the elimination of traffic signals on SR 37 is expected to ease traffic congestion along the northbound I-69 and SR 37 exit (Exit 205) during PM peak hours. 

The 2010 SR 37 Mobility Study conducted an intersection capacity analysis based on 2010 traffic counts and 2036 projected traffic counts.

After improvements are made, all intersections will operate at the highest level of service (A) through 2036. In addition, the study found increased safety due to the reduction of stop and go congestion. This means that your commute time will decrease and motorist safety will increase. 

6. I don’t travel on SR 37 daily, but I do cross it at very busy intersections. Once complete, how will these improvements impact me?
The SR 37 project will create separated grade intersections which means the cross streets (126th, 131st, 135th, 141st and 146th Streets) will no longer intersect SR 37 but instead will “go over” the road in a tear drop roundabout alignment. With the removal of the traffic signals, traffic will move more fluidly through the intersections and significantly decrease wait times for motorist traveling east/west. 

In addition, the roundabout intersections will increase pedestrian connectivity with east/west sidewalks that flow with traffic rather than crossing it. Crosswalks will also be installed. 

7. How much will this project cost and who is funding the improvements? 
The SR 37 improvement project will cost an estimated $124 million to complete.The State of Indiana’s Department of Transportation (INDOT) will cover a bulk of the costs at $100 million, and the City of Fishers and Hamilton County will each contribute $12 million. 

8. Will my taxes go up to help pay for this project?
There are no anticipated tax increases to fund this project .

9. Since this project is a partnership between various agencies, who will control the construction schedule and maintenance of traffic?
While all agencies will be involved in the development of the project, the City of Fishers is responsible for the design, construction and maintenance of traffic and all communication regarding traffic and lane closures. 

During construction and seven years after completion, SR 37 will be maintained by the City of Fishers. After the seven years, the road will be returned to the State of Indiana and maintained by INDOT.

10. What is the timeline for the improvement project on SR 37?
The final design of the project will be determined over the next two to three years as environmental and design studies are completed with opportunity for public input. Once design is complete, the construction period is expected to last approximately three years. A project timeline is available with additional details. 

11. How will the project construction impact my commute?
While there will be lane restrictions and periodic lane closures, the road will not be closed for any length of time during construction. The City of Fishers will diligently communicate with the public, businesses and news media to help disseminate updates throughout the duration of the project to reduce impact as much as possible.

12. How will this improvement project benefit businesses located along SR 37?
Because of traffic congestion, more and more residents are already seeking alternate routes—avoiding SR 37 and overloading secondary routes. By improving the corridor’s flow and mobility, potential customers are less likely to avoid the corridor which could lead to more business for the area establishments. 

In addition, by improving bicycle and pedestrian mobility and connecting the community, the SR 37 area businesses could attract additional customers. Historically, corridors that are friendly to alternative modes of transportation enjoy increased economic development opportunities.  

13. What is the environmental impact of this improvement project?
The impact of the planned separated grade interchange improvements to SR 37 are minimal compared to large highway expansion projects that include adding additional travel lanes.

While the detailed impacts will be identified in the Environmental Assessment to satisfy the National Environmental Policy Act (NEPA), it is anticipated that the project will have only minor impacts to social, environmental, economic, or ecological resources. There are no residences or businesses that are anticipated to be displaced because of the SR 37 improvements.

14. What is the detour route for the SR 37 project?
The SR 37 project will be constructed under traffic such that two northbound and two southbound traffic lanes will be open at all times. If detour routes are needed for the cross streets during construction, they will be identified during the detailed design phase to handle local traffic needing to access and cross SR 37.

15. Where can I find current updates and more info on this project?  
Residents, business owners and other stakeholders are encouraged to subscribe to SR 37 Project Emails alerts and check Project Updates regularly. 

Routine construction updates for the City of Fishers are available by subscribing to Drive Fishers emails, by viewing weekly construction updates or by following @DriveFishers on Twitter.
