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.
(See Video Clips)
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.
