Start Date: January 16, 2018
Estimated End Date: late spring 2018

Project Background:

Work on this project consists of removing the existing, outdated traffic signals and equipment in the west ramp of the intersection and installing new ones. Other elements of the project include curb ramp replacement with ADA-compliant ramps (American with Disabilities Act), signing and striping. The project was suspended in late 2017 due to design changes and material lead times.

Normal working hours will be from 7 a.m. to 6 p.m., with lane closures from 9 a.m. to 2 p.m., Monday through Friday. In special cases these hours may be extended. Motorists should be prepared for right-lane closures and lane shifts during construction hours. Intermittent nighttime operations and temporary traffic stops are possible when crews remove and replace the mast arms.

Long Road Reconstruction | The City of Greenwood Village 

The City of Greenwood Village Public Works Department is reconstructing the pavement on East Long Road, East Long Lane, and Jackson Street. The project will consist of pavement reconstruction, upgrading of the drainage system and enhancement of the streetscape section. Identified goals include: the mitigation of winter icing conditions, traffic calming and improved pedestrian safety. 

Long Road will open to through traffic on Monday, December 11, 2017. However, work will continue as weather permits through the winter with utility and grading activities during non-rush hour periods with one way flagging operations. Hours of one way flagging will occur between the hours of 8:30 a.m. and 3:30 p.m. Monday through Friday and 7 a.m. to 7 p.m on weekends. The remaining pavement reconstruction work on Long Lane and Jackson Street will commence in late Spring with only short term weekend closures expected.
