*All projects are subject to change

Winter - Boone County Highway Department

1. Sycamore Street Bridge Rehabilitation

The reconstruction project for the Sycamore Street bridge is scheduled to begin Feb. 10, 2020. During construction the bridge will be closed to through traffic. 

Road closures anticipated:

  • Sycamore St. will be closed between Zionsville Rd. and US 421.
  • The trail system under the bridge connecting Lions Park to Creekside Park will be closed.
  • The pedestrian bridge and trail system along Sycamore St. are anticipated to remain open to the public with only periodic closures for safety.

Estimated completion: Aug. 28, 2020

Background: This project involves the reconstruction of the road bridge deck and bridge railing systems and provides new decorative lighting on the rehabilitated bridge.


2. Zionsville Road

The road opened to all traffic on December 23. While roadwork has been suspended for the rest of the winter season, Duke Energy will continue to install the decorative street lights. Final construction activities will take place in the spring of 2020 with no further full closures expected. 

Estimated completion: May 2020

Background: This project involves the widening of Zionsville Road, which will go from two to three lanes when a center turn lane is added between Technology Center Drive and 106th Street. The project also includes adding a bike path on the west side of the road.

3. North-South Connector

Bids have been awarded and contract documents are being finalized. Preliminary construction activities are expected to begin in February 2020 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., from June 1 - Aug. 1, 2020
  • 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: Design has begun on a new roadway segment that 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 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.

4. Irongate Drainage Improvement Project

A pre-construction meeting took place in February. 

Road closures anticipated: No full-road closures are currently expected. The south lane of eastbound Oak St. will be closed during the construction between Irongate Dr. and the Walgreen’s entrance.

Estimated completion: TBD

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 

This project is currently underway. The sewer extension connects the intersection of CR 500 S. with the Zionsville School’s sport complex just to the north.

Road closures anticipated: Closure at CR 500 S (Whitestown Road) immediately west of CR 875 E. on Feb. 17 – 19, weather dependent.

Estimated completion: Spring 2020

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: TBD

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. This project went out for bid in January 2020. A preliminary schedule will be announced soon.

Estimated completion: End of 2020

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: July 2020


9. CR 400 South Reconstruction and Widening

As a result of new information from Boone County REMC, this project is postponed to late summer 2020 to allow that organization to complete the relocation of utility poles on the north side of CR 400 S. Due to their restrictions in scheduling power outages necessary to complete this work, they cannot begin until May 1, and require eight to 10 weeks to complete tasks. Road reconstruction cannot begin until all utility poles have been moved.

Road closures anticipated: Full road closure of CR 400 S. for approximately .5 miles west of CR 875 E. is expected, dates TBD.

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 the utilities will be relocated over the winter with road construction beginning 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

Ford Road and Bloor Lane Roundabout

Work is nearly complete on new landscape and hardscape elements within the center of the roundabout.

Background: This roundabout includes low masonry walls and upgraded plant materials. The tree at the center that was planted by a local Eagle Scout candidate will be preserved.

Mulberry St. Pathway 

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

Road closures anticipated: None anticipated

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.
