Construction began on the Holdom overpass project in Burnaby yesterday.
The elevated four-lane overpass will extend Holdom Avenue over the CN Rail corridor and Still Creek to connect with Douglas Road so road users won't get stuck behind passing trains.
The Vancouver Fraser Port Authority, which is directing the project, has begun installing fencing for tree protection, silt and wildlife along the Central Valley Greenway, according to a news release.
The port authority said the work will not impact cycling or pedestrian access to the Central Valley Greenway, including the portion of the path between Douglas and Kensington.
"Please drive slowly, use caution and obey signage and traffic personnel," said the release.
Signage will be in place prior to any closures to inform drivers of any traffic pattern changes.
The overpass is meant to improve traffic flow and safety for the Burnaby community, increase trade capacity and efficiency, and reduce greenhouse gas emissions, according to the port authority.
The overpass is expected to be open to the public in spring 2027.
The City of Burnaby will take ownership of the overpass once it is complete.
The project is expected to cost about $200 million, funded by the federal government, the port authority and CN, the port authority told the Burnaby NOW in July.
