Construction of the SR 400 Express Lanes will follow all applicable, current GDOT policies and standards including the Department Construction Manual, available online at:
Environmental studies are currently being conducted in compliance with the NEPA and the draft Environmental Assessment is expected to be completed in early 2020 and will be made available to the public for review and comment prior to and during the Public Hearing Open Houses.
Road closure and major construction would be communicated to stakeholders along the corridor in a timely manner by the project team through the project website and email. The project will continue to maintain a project hotline number throughout construction which will be communicated to the public.
GDOT will review construction time periods and lane closures during the Request for Proposal (RFP) process that defines the scope of work for the Developer to follow.
GDOT has seismic monitors that will be placed as needed and in accordance with GDOT policies. As part of the project, inspectors will be required to make sure standards are being met.
Early right-of-way acquisition will take place with certain properties beginning in late 2019. Removal of structures, foundations, and general grading will be performed. Typical GDOT erosion control measures will be implemented. These areas may be used by the Developer for construction activities and project needs. Final grading and site cleanup will commence at the end of work activities. This work includes reestablishment of natural vegetation and removal of any silt fence and other erosion control materials. Landscaping is not performed by GDOT contractors and is usually implemented under a separate agreement and by permission from GDOT with a local government or other stakeholder. These newly acquired properties will become GDOT right-of-way and as such, GDOT cannot commit to any additional landscaping beyond grassing due to maintenance concerns and the imminent need for the land to construct the project. GDOT does not perform maintenance of landscaped facilities within GDOT right-of-way, only allows its right-of-way to be landscaped and maintained by others under separate agreements. If a landscaping plan and agreement is in place, this work is typically performed at the completion of construction activities in the affected areas. Construction of the project is currently scheduled to begin in 2023.
Construction materials will be placed and stored in GDOT right-of-way in compliance with the Occupational Safety and Health Administration (OSHA) standards. GDOT will follow established policies on the storage and handling of flammable and hazardous materials.
Generally, when constructing the SR 400 Express Lanes, vehicles will access the project from SR 400 or from roads that are part of the project; however, there may be constructability needs in areas that may require access by local roads during certain points of construction.
Noise barriers are built by the Developer, usually near the end of construction phase of the project. The construction phase of this project is currently proposed to start in 2023 and conclude in 2027.
Detailed construction plans and schedules outlining phasing are not currently available and will be designed after multiple rounds of public comment and in coordination with the Developer once the project is Let (awarded) in 2021/2022. Please see page 5 for general schedule information.
