In 2016, the City of Ankeny will be widening the existing NE 36th Street bridge over Fourmile Creek from two lanes to four lanes. In 2017, the existing two-lane rural roadway from just east of Highway 69 to just west of NE Delaware Avenue will be reconstructed into a new four-lane divided urban street with raised medians and left turn lanes. The existing rural ditches will be replaced with storm sewer intakes and pipes.
NE 36th Street Bridge Widening Over Fourmile Creek (2016 Construction)
Why is this project necessary?
The purpose of the project is to widen the existing bridge from two lanes to four lanes with an 8' wide sidewalk in advance of the NE 36th Street Reconstruction - Phase 2 project.
How long will construction last?
Construction of the bridge widening is anticipated to last the entire construction season, from April through November 2016.
How will the project be constructed?
The bridge widening is being staged to maintain two-way traffic on NE 36th Street throughout the duration of construction. The widening will occur in separate stages on both the south and north sides of the bridge.
What should motorists be aware of when traveling through this area?
The speed limit of NE 36th Street between NE Trilein Drive and NE Briarwood Drive will be reduced to 25 mph during construction for the safety of both the construction workers and the motorists traveling adjacent to the project.
Will pedestrian traffic be allowed in the area?
For everyone's safety, pedestrian traffic on NE 36th Street in the vicinity of the bridge will be prohibited while lane widths are reduced on the existing bridge. The lane width reductions are necessary to provide sufficient clearance for the construction workers as they perform their work.
What amenities are being provided?
The north side of the bridge widening will include additional width to accommodate an 8' wide sidewalk with a safety rail separating pedestrians from vehicular traffic. In addition, the preliminary grading of a wetland and water quality basin will be undertaken on City property south of the Outdoor Education Center.
How will the City notify the public about project updates?
The City will use its website, news releases, email notifications and social media channels to inform the public of any updates on this project. The City appreciates the patience and understanding of its citizens while it completes this important project.
NE 36th Street Reconstruction - Phase 2 (2017 Construction)
Why is this project necessary?
The purpose of the project is to provide increased traffic capacity and mobility due to the substantial growth within this corridor. The improvements will help improve safety for both motorists and pedestrians. For reference, the Phase 1 project consisted of the reconstruction of NE 36th Street from just west of NE Delaware Avenue to just east of Interstate 35 in 2012, in conjunction with the opening of the NE 36th Street Interchange.
How long will construction last?
Construction of the roadway improvements is anticipated to last the entire construction season, from April through November 2017. Depending on construction progress and weather conditions, the landscaping and permanent surface restoration will occur in either Fall 2017 or Spring 2018.
How will the project be constructed?
The roadway reconstruction is being staged to maintain north/south traffic at the NE Trilein Drive and NE Briarwood Drive intersections for as long as possible. However, through traffic on NE 36th Street from Highway 69 to NE Delaware Avenue will be prohibited for the duration of construction. Closing NE 36th Street to traffic will allow for the project to be completed in one construction season and will also reduce project costs. The signed detour route for through traffic on NE 36th Street will be Highway 69, NE 18th Street, and NE Delaware Avenue.
What should motorists be aware of when traveling through this area?
NE 36th Street will be closed to through traffic at the east leg of the NE 36th Street and Highway 69 intersection. Local traffic will be allowed to access the entrance to Casey's and to the Bentgrass Townhomes. NE 36th Street will be closed to all traffic at the west leg of the NE 36th Street and NE Delaware Avenue intersection.
Will pedestrian traffic be allowed in the area?
For everyone's safety, pedestrian traffic along the NE 36th Street corridor will be prohibited while the roadway and sidewalk are being constructed. The pedestrian crossings at NE Trilein Drive and NE Briarwood Drive will remain open for as long as possible.
What amenities are being provided?
A new traffic signal will be installed at the intersection of NE 36th Street and NE Trilein Drive. The north side of NE 36th Street will have an 8' wide sidewalk from Highway 69 to NE Delaware Avenue. In addition, the wetland and water quality basin on City property south of the Outdoor Education Center will provide stormwater quality and quantity management. The street right-of-way will be landscaped with street trees and ornamental grasses.
How will the City notify the public about project updates?
The City will use its website, news releases, email notifications, and social media channels to inform the public of any updates on this project. The City appreciates the patience and understanding of its citizens while it completes this important project. View an exhibit of the proposed improvements (PDF).
