Key Road Projects

Below is a list of projects from the Street & Stormwater Department and Wastewater Department. 

*All projects are subject to change

North-South Connector

The intersection of Whitestown Road and CR 875 East is complete and open to traffic. 

Road closures anticipated:

  • CR 875 E. between CR 550 S. and CR 575 S. through November 30.
  • CR 850 E. south of Oak St. beginning in the spring of 2021

Estimated completion: Summer 2021

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 will also 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.

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: November 2020

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.

Estimated completion: TBD

Progress status update: The construction of the new sanitary sewer along Oak St. has been temporarily halted at Lakeview Dr. and westward due to the discovery of a Vectren gas line that was not previously identified, or a proper location accurately represented. As a result, the excavation at the intersection of Lakeview Dr. and Oak St. has been protected using steel plates for the time being until a plan to avoid the conflict of the gas line has been developed. A timeline for resolution is not known at this time, but all parties are working on a solution to allow this important project to continue.

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 assessed interest, 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.

North Regional Sewer

This project takes sewer to the northeastern sewer service area of town through the Holliday property. 

Estimated completion: September 2020

CR 400 South Reconstruction and Widening

Utility work along CR 400 South will begin on or after September 28. Drivers should be prepared to follow the directions of traffic personnel. Actual road reconstruction is likely delayed until the spring of 2021. If favorable weather is experienced in November and December, this work could still occur this year.


Estimated completion: TBD

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

CR 500 South Reconstruction and Widening

Design is ongoing. It is anticipated that road construction will begin in spring 2021.

Road closures anticipated: Full road closures are anticipated.

Estimated completion: Spring 2021

Background: This project improves and widens CR 500 South from CR 875 East 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.

800 East

800 East will be widened and resurfaced by the developers of the Pemberton and Hampshire subdivisions. Some of this work is planned for yet this year once the utilities have relocated their poles to allow for the expansion of the road. Until then we will use temporary measures to address deficiencies.


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.
