ABBOTSFORD — Drivers can expect more traffic changes heading eastbound on Highway 1 at Mount Lehman Road as work to expand the Fraser Valley corridor continues.

Starting Monday, August 17, crews will be installing girders for the expanded Mount Lehman structure.

As a result, eastbound traffic will cross over to flow in both directions, one lane each, in the westbound lanes.

The southbound off-ramp at Mount Lehman will stay open. Northbound Mount Lehman Road and eastbound Fraser Highway traffic will have detours. On-ramp access is unaffected.
