Project Description: Green Meadows Road is a two-lane street intersecting with a four-lane divided roadway at Forum Boulevard resulting in what had been an all-way stop with six lanes of busy traffic. The intersection was identified in the City of Columbia’s 10-year plan for the 2015 Capital Improvement Sales Tax as needing improvement. The goal of the project was to increase safety and reduce congestion by removing the all-way stop and constructing the roundabout. The intersection improvement project included a partial dual-lane roundabout, utilities, sidewalks, crosswalks, pedestrian safety islands, street lighting and stormwater improvements.

Project Status: The Green Meadows and Forum Boulevard intersection improvement project opened 30 days ahead of schedule on Oct. 24. Emery Sapp and Sons, Inc. began construction of the roundabout on July 8 with an estimated construction schedule of 150 days. If everything stays on track, the project should be completed at least 30 days ahead of the original plan. This includes some additional work scheduled to occur on Forum Boulevard over the next 1-2 weeks to remove the temporary crossover lanes and finish seeding the median. While the crossovers are being removed, there will continue to be some temporary lane restrictions in the area.

Oct. 29, 2019: It’s cold today, but the contractor’s crews are on the job repairing the median on Forum Blvd where the temporary crossover lanes had been installed for the construction of the Green Meadows and Forum roundabout. Including this work, on this cold cloudy day, the project remains on schedule to be completed 30 days ahead of the original plan (the roundabout opened on Oct. 24). Watch for ongoing lane restrictions.
Oct. 24, 2019: Green Meadows and Forum Boulevard intersection improvement project opened 30 days ahead of schedule on Oct. 24.
“Most importantly, the Forum and Green Meadows Roundabout provides a safer intersection for pedestrians, nonmotorized transportation users and motorists,” Public Works Director David Nichols said. “We really appreciated the public’s patience and support during the construction process and the related road closures. It was a community effort.”
Oct. 1, 2019: On the home stretch…(but still a lot of work to go): The contractor for the new roundabout and improvements at the intersection of Forum Boulevard and Green Meadows estimates that the project is approximately 75 percent complete with a possible opening date between Oct. 20 and Nov. 1, weather permitting. (This timeline estimate is subject to change.) Crews will be working on street lighting, sidewalks, landscaping and then finishing up with striping and signage. Once the roundabout intersection is fully open, the crossovers will be removed and the center median will be restored on Forum Boulevard. Watch social media for updates as the project nears completion … most likely ahead of the originally announced schedule of 150 days.
Sept. 20, 2019: Emery Sapp and Sons, Inc. crews are using a concrete pump to lay the pavement on Green Meadows Road this morning as part of the Forum and Green Meadows roundabout project.
Sept. 17, 2019: Emery Sapp and Sons, Inc. crews are working on pouring curbs today. Weather looks promising for another productive week. Crews hope to begin some pavement this week, weather permitting. The project currently remains ahead of the originally announced schedule, weather permitting.
Sept. 3, 2019: East Green Meadows has now closed at Forum Blvd for construction. A temporary three way stop has been installed. Motorists can now access both northbound and southbound Forum Blvd from West Green Meadows. (There is no outlet to Nifong from West Green Meadows so this is not a detour…continue straight on Forum.) The east side of the roundabout construction will close East Green Meadows at the intersection. To access Forum from the east motorists should use major roads as alternate routes when possible. The roundabout construction currently remains ahead of schedule, weather permitting.
Aug. 23, 2019: Contractor crews are working to finish pouring sidewalks on the west side today and Saturday.
Aug. 13, 2019: Weather permitting, the contractor plans to make the last roadway concrete pour of phase 1 (west side) this week. They will then begin installing street lighting, sidewalks and final grading in phase 1 beginning next week, weather permitting. The work currently remains on schedule. A planned schedule and complete details for phase 2 (east side) will be announced as details become available.
Aug. 5, 2019: Crews have begun concrete work; on track to finish west side curbs today.
July 30, 2019: The sheepfoot roller is compacting the subgrade. Crews are working to create a stable base for the roundabout by first removing and then compacting the subgrade (soil). This will be followed by spreading base rock and compacting it some more. Then, after some subterranean street light infrastructure is installed, concrete operations can begin. The project remains on schedule despite losing a few days due to a utility relocation issue and weather. (Watch Video)
July 19, 2019: The contractor will return to begin installing stormwater infrastructure (pictured) next week, weather permitting. In the meantime, there are still some private utility lines in the construction zone that private utility crews will be moving early next week before construction crews can begin digging again.
July 15, 2019: Crews are working on the west side of the Forum and Green Meadows roundabout. Forum Blvd is restricted to one lane in each direction throughout the 150-day project. The east side of Green Meadows is currently open but is subject to announced lane restrictions.
— Motorists who need to access neighborhoods to the west side of the intersection must use Doral Drive (no outlet).
–Southbound motorists who need to access Nifong must continue on Forum Blvd.

July 8, 2019: Construction crews are creating crossover roads on Forum Boulevard this week, and City of Columbia Utilities is completing its work, in preparation for roundabout construction. Forum Boulevard has been temporarily reduced to two lanes for the duration of the project. Green Meadows is scheduled to close on the west side with possible restrictions to be announced on the east side if/when needed. Forum will remain open but some delays are possible. Please drive slowly in the work zone and when using alternate routes.
July 3, 2019: The contractor for the project plans to start construction of the temporary crossovers on Forum Boulevard beginning Monday, July 8. Forum will be reduced to one lane in each direction starting Monday. Expect minor delays and please use signed detours/major streets as alternate routes whenever possible. Please drive slowly and with caution around/through the work zone as well as on alternate routes.
June 27, 2019: Beginning July 8, the City of Columbia Public Works Department plans to begin construction of a partial dual-lane roundabout at the intersection of Forum Boulevard and Green Meadows, weather permitting. Emery Sapp and Sons, Inc. is the contractor for the project, which is expected to take approximately 150 days to complete. Work will be done in phases to reduce the impact on traffic as much as possible. Before work on the roundabout begins, temporary paved crossovers will be installed on Forum Boulevard north of the Green Meadows intersection to funnel traffic to one lane each way during construction. Access to Green Meadows via Forum Boulevard will be closed on the west side of the intersection during the first phase of construction. However, neighborhoods to the west of the project will be able to access Forum Boulevard via Doral Drive. Once the west side of the roundabout is complete, work will begin on the east side of the intersection. (Press Release)
May 30, 2019: Utility work is being performed at the project site in preparation for construction to begin in July. Complete details will be available soon.
April 29, 2019: Speed humps and speed tables were installed on Canterbury Drive and Scottson Way prior to construction of the Forum Boulevard & Green Meadows roundabout, a Capital Improvement Program project approved by City Council.
Despite a rainy spring, the City of Columbia Public Works Street Division completed four Council-approved traffic calming projects in April. The projects included a pedestrian safety project on Walnut Street, a Neighborhood Traffic Management Program (NTMP) project on Rainforest Parkway and two Capital Improvement Program (CIP) calming projects on Canterbury Drive and Scottson Way. The projects consisted of installing speed humps and speed tables to improve safety by slowing traffic. The total estimated investment for all four projects was $50,000. All projects passed through the City’s public involvement process. More information about these and additionally planned projects is available at CoMo.gov/PublicWorks/Construction.
