170th Street Reconstruction with Meredith Drive
Project Status Update, 05/18/2023:
170th Street is closed from Plum Drive to north of Waterford Road to complete construction of Stages 2A and 2B. Plum Drive remains open for school access. Waterford Road is closed at the intersection with 170th Street. The 170th Street mainline has been paved. The remaining paving work for intersections, cross-overs, turn-lanes, and intake boxouts is underway. The outside lanes of 170th Street from Meredith Drive to Waterford Road will be closed to allow sidewalk, trail, fence, and driveway installation in previous stages.
Meredith Drive has been paved and is re-opened west of 170th Street. The outside lanes of Meredith Drive east of 170th Street are closed to allow sidewalk, trail, bio-retention cells, and final grading to be completed. Please use caution as the Contractor continues work in the outside lanes.
Stage 2 will be re-opened by Memorial Day. Stage 3 is currently scheduled to close on Wednesday, May 31. Access to the school will be via Plum Drive to the north parking lot only.
Please see the maps below for the locations of the stages. An official detour route has been established, and the Police and Fire Departments have been notified of the closed areas.
This project will reconstruct 170th Street from Meredith Drive to Waterford Road as well as approximately 1/4 mile of Meredith Drive, east of 170th Street. Both roads will be reconstructed as a four-lane roadway with left-turn lanes, including grading and storm sewer. 170th Street will include the City’s Complete Street policy, with a 5’ sidewalk and 10’ separate bike lane along the west side of the road. Meredith Drive will include a 10’ trail along the north side of the road. A Traffic Signal will be installed at 170th Street and Meredith Drive. This project has received a State Transportation Block Grant to assist with funding. 170th Street is known as "Alice's Road" in Clive and Waukee.
The Contractor for this project is C.J. Moyna & Sons, LLC, and Progressive Structures, LLC, joint venture. This project is a two-year project and is anticipated to be completed in late 2023.
Latest News and Staging Information:
170th Street from Plum Drive to Waterford Road will be paved April 27-28. Meredith Drive west of 170th Street is scheduled to be paved the week of May 2. Detours are posted. See additional details below.
We have had several questions about the pavement in front of the school. The staging on the 170th Street project is designed so that Radiant Elementary is more accessible during the school year. The portion from Hickory Drive to Plum Drive (Phase 3 - see maps below) will be shut down and replaced after school is out for the summer. We will get a much better product on the final paving for years to come if we wait to do this Phase 3 section as a single mainline pavement pour. The north end (Phase 2) needs to be completed now so that it can used for access to the school in the summer months. Final sidewalk and trail installation will then be done in the fall. If Phase 2 is not done now, this would definitely stretch into a three-year project. This phasing was planned to give us the best chance of completing this project in two years.
Unfortunately, the winter was particularly hard on the Phase 3 temporary pavement due to the freeze-thaw cycles. Also this spring, the private development has begun paving to the west of 170th Street; we do not control that schedule, and although there are benefits to that paving occurring ahead of our mainline paving, it is causing significant additional wear-and-tear on the temporary pavement. The City Contractor has been on site numerous times for maintenance on the Phase 3 temp pavement and will continue to maintain it this spring.
We apologize for the frustration and inconvenience of this project, and we appreciate your patience as the work progresses. The final product of a four-lane 170th Street will be a benefit to our community.
Access and Work Zones:
This project will be completed in stages. Please follow posted signs and detours for routing around construction. Please check back here for updates on closures as work progresses.
Maps will be posted to this webpage with additional information. The schedule is subject to change based on weather, conditions in the field, and contractor coordination. Check back to this page for project updates. As always, please use caution in the construction zone and obey all traffic control, for your safety and the safety of others. We appreciate your patience, thank you for your cooperation.
Please see the "Staging Map Below" for project stages. This is a two-year project. The goal for Year 1 was to get Stages 1A, 1B, and 1C completed; due to weather and utility delays, this may be adjusted. Year 2 will start with Stage 2, with Stage 3 taking place after school is out for the summer in 2023.
