Q. Why is this project needed?

A. This project was identified by the City of Fishers, Hamilton County Highway Department, City of Noblesville, and INDOT for a number of reasons:
  • To alleviate traffic congestion

A 2010 SR 37 Mobility Study, commissioned by the Hamilton County Commissioners, reviewed the current levels of service (LOS) for the intersections along the corridor and studied possible infrastructure upgrades to improve traffic flow and service. The study concluded that most of the intersections are currently operating at an unacceptable level of service.

In addition, SR 37 is a people mover to and from I-69. The INDOT controlled, signalized intersections along the corridor are set-up to keep traffic moving north and south. Nearly every day, this creates significant back up on the cross streets as commuter traffic heading east/west have short light times and often lead to delays during peak travel times.

  • To proactively address future growth and additional traffic

Each day, SR 37 sees more than 50,000 vehicles per day. As growth continues to come to Hamilton County and surrounding cities, this number is expected to increase. With intersections already near capacity, it is important to make infrastructure improvements to accommodate projected growth and keep the intersections operating now and into the future.

  • To improve connectivity in our community

Currently, the intersections along SR 37 are not encouraging of use by  pedestrians and cyclists and is a barrier to creating a more connected community.  Many residents have expressed interest in alternative modes of transportation, but are concerned that SR 37 is impossible to cross during peak times of the day. SR 37, quite literally, creates a dividing line down the center of our community. 

Q. What intersections will be improved as a part of this infrastructure project?

A. The infrastructure project announced on 12/10/15 includes the intersections of SR 37 and 126th, 131st, 135th, 141st and 146th streets.

Q. Once complete, what will SR 37 intersections from 126th to 146th streets look like?

A. The improvement project includes the rehabilitation of 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.

A rendering of a rehabilitated intersection can be found here.
 
Please note, as project design moves forward additional information will be made available for each rehabilitated intersection. Make sure you sign up for updates to receive more information as the project moves forward. 

Q. The improvement projects include a separated grade with roundabout interchanges; what other alternatives were studied when evaluating this project?

A. A 2010 SR 37 Mobility Study, completed by the Hamilton County Highway Department, the City of Fishers, the City of Noblesville, and INDOT, was commissioned to evaluate the merits of a grade separation at the existing intersections. The study showed that replacing the traffic signals with interchanges would significantly improve safety and mobility through the corridor without the need for additional travel lanes. 

Q. I travel SR 37 to and from I-69 every workday. Once complete, how will this impact my commute?

A. 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 St. 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. The following was observed:

As demonstrated in the table above, 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. 

Q. 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?

A. 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. 

Q. How much will this project cost and who is funding the improvements? 

A. The project being completed between 126th Street and 146th Street is anticipated to cost approximately $124 million. The State of Indiana’s Department of Transportation (INDOT) will cover a bulk of the costs at $100 million, and local contributions will be $24 million with both the City of Fishers and Hamilton County each contributing $12 million. 

Q. Will my taxes go up to help pay for this project?

A. There is not any anticipated tax increases to fund this project .

Q. Since this project is a partnership between the City of Fishers, INDOT and Hamilton County, who will control the construction schedule and maintenance of traffic?

A. While all agencies will be involved in the development of the project, the City of Fishers is responsible for the design and construction of the improvement project. Fishers will be responsible for the 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.

Q. What is the timeline for the improvement project on SR 37?

A. 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.

Q. How will the project construction impact my commute?

A. The City of Fishers is responsible for the construction and maintenance of traffic during construction. 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.

Q. How will this improvement project benefit businesses located along SR 37?

A.  It is no secret to anyone whom travels SR 37 that the road is near capacity. In the 2010 SR 37 Mobility Study , many of the intersections were operating at unacceptable levels of service, and as the region grows, more commuters are expected to travel this road. Because of traffic congestion, more and more residents are already seeking alternate routes—avoiding SR 37 at all cost 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.  

Q. What is the environmental impact of this improvement project?

A. 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.

Q. What is the detour route for the SR 37 project?

A.  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 in order to handle local traffic needing to access and cross SR 37.

Q. Where can I find current updates on this project?  Where do I go to get more information?

A.  Current information and timely updates about this project during the detailed design phase and the construction of the project can be found on the Fishers website at www.Fishers.in.us/SR37Project.
