3. North-South Connector

Preliminary construction activities have begun and full construction is expected in spring 2020. The project is anticipated to take a full construction season.

Road closures anticipated:

  • Intersection of Whitestown Rd. and CR 875 E., beginning on or after June 22 through Aug. 21
  • CR 875 E. between CR 550 S. and CR 575 S., dates TBD
  • CR 850 E. south of Oak St., dates TBD

Estimated completion: September 2020

Background: A new roadway segment will connect the intersection of CR 850 E./Cooper Rd. with CR 875 E. to the north. The design includes a roundabout at the intersection of CR 850 E./Cooper Rd. and Oak St. as well as a roundabout at the intersection of CR 875 E. and Whitestown Rd. The project is also expected to include a 10-foot multi-use path.

Note: There are no planned closures for the south roundabout on CR 850 East/Cooper Road and Oak Street. It is planned to be constructed under traffic.

4. Irongate Drainage Improvement Project

This project is currently underway.

Estimated completion: COMPLETE

Background: This project is intended to mitigate localized street flooding in the Irongate subdivision. The project involves the installation of a new storm sewer pipe along the south side of Oak St. from Irongate Dr. to just west of Ford Rd.

5. Phase I Gravity Sewer on CR 875 East 

The sewer extension connects the intersection of CR 500 S. with the Zionsville School’s sports complex just to the north.

Estimated completion: COMPLETE

6. Phase 2 Gravity Sewer on CR 875 East

Part of this project is tied to the North-South Connector project. This project begins at CR 550 S. and travels south picking up several existing homes via gravity.

Estimated completion: End of 2020

7. Oak Street Sewer

The sewer will be located on the north side of Oak St. and will extend west of Cooper Rd. traveling east to just west of Irish Hill. A preliminary schedule will be announced soon.

Estimated completion: August 2020

Background: All residents along the side streets of Oak Street who are in the direct location of the sewer project are being considered for sewer. This includes residents as far west as 800 East and as far east as 950 East. As a first step, the Wastewater Department is assessing interest and asking residents in the area to complete a survey. The Town needs greater than 50% buy-in from the neighbors to run sewer down a street and all neighbors will be asked to contribute in the cost. However, residents will not be forced to connect.

8. North Regional Sewer

This project takes sewer to the northeastern sewer service area of town through the Holliday property. This project is expected to go out for bid in February 2020.

Estimated completion: August 2020


9. CR 400 South Reconstruction and Widening

Utility relocation is underway. Following the utility relocation work, beginning on or after Aug. 23, CR 400 South to the west of CR 875 East for approximately .5 miles will be closed to through-traffic. Local access to homes will be maintained. This will be the final phase of the CR 400 South widening, repair and resurfacing project.

Road closures anticipated: On or after Aug. 23, the road will close to through-traffic.

Estimated completion: Fall 2020

Background: This project includes the widening, repair and resurfacing of CR 400 S. to the west of CR 875 E. for approximately .5 miles.

10. CR 500 South Reconstruction and Widening

Design is ongoing. It is anticipated that road construction will begin in spring 2020.

Road closures anticipated: Full road closures are anticipated.

Estimated completion: Fall 2020

Background: This project improves and widens CR 500 S. from CR 875 E. approximately .4 miles to the west. This project will reconstruct a portion of the road and widen the existing width to 24 feet. This project is funded partially from private developer funds.

Other Projects

Templin Road Bridge Reconstruction (Boone County Highway Department)

The shoulder of this bridge is currently closed. 

Background: The Templin Road bridge over Eagle Creek was inspected last fall and an engineering firm has been hired by the Boone County Highway Department to work on design of a complete bridge replacement. The shoulder is currently closed and will remain closed until the bridge reconstruction project begins in 2021.

Mulberry St. Pathway 

Design work is nearly complete for this multi-use pathway. Construction is expected to begin in spring 2020.

Estimated completion: December 2020

Background: This pathway will be constructed along the north side of Mulberry St. from Governors Ln. to the roundabout at the intersection of Ford Rd. and Mulberry St.

Municipal Services Building Pathway 

Design work is nearly complete. It is expected that this project will be awarded for construction prior to the end of this year, and construction will follow in the spring of 2020.

Estimated completion: December 2020

Background: A multi-use pathway will be constructed along the west side of the Municipal Services Building. This project will provide a route from the sidewalk system along Parkway Dr. south to Starkey Trail.

CR 300 South Corridor Project

Through a grant from the Indianapolis Metropolitan Planning Organization, the Town of Zionsville has partnered with the Boone County Highway Department to conduct a corridor study along CR 300 S. from CR 800 E. to the Boone/Hamilton county line. The purpose of this study is to identify a preliminary scope and a potential design of future road widening and intersection improvements considering feasibility, costs, impacts to properties, environmental concerns and bridge needs. 

While there is one known bridge replacement project planned within the next four years, there are no identified intersection or road projects at this time. The information learned from this study will initially guide bridge design as these structures are maintained and replaced as needed. Future intersection or roadway capacity projects will not be undertaken until the volume of vehicles and levels of service justify the improvements.
