About the project
232nd Street connects communities north of Highway 1, including the eastern section of Walnut Grove and Fort Langley, with the rest of Langley.
As part of the Roberts Bank Rail Corridor Program, the 232nd Street Overpass Project proposes to build a two-lane overpass that will replace the current street-level crossing of the Canadian Pacific Rail tracks between 75th Avenue and 76A Avenue, eliminating delays for drivers, cyclists and pedestrians, and allowing for the possible future westward extension of the Rawlison rail siding.
Funding partners include Port Metro Vancouver, Transport Canada and Canadian Pacific Rail.
Proposed Project Components:
- Two 3.5-metre lanes with a 1-metre shoulder on each side
- A shared pedestrian/cyclist lane on both sides of the overpass with a protective concrete barrier
- A vertical realignment of 75th Avenue to connect with 232nd Street at approximately 4.5 metres above existing ground level
- A guard rail for the full length of the overpass
- A width of approximately 16 metres
- Overhead lighting for the full length of the overpass
One design change made in July 2012, is that the project will now include a roundabout at the intersection of 72nd Avenue and 232nd Street. Instead of reinstating the intersection as per the current conditions, we will now be constructing a one lane roundabout to improve both mobility and safety. The project team is collaborating with both the Township of Langley and Ministry of Transportation and Infrastructure. Once complete, access will remain the same as it is today and during construction, appropriate detours and signage will be in place.
Construction and traffic management
First to be built is the temporary paved detour road in order to ensure a smooth transition for traffic movement for when the overpass is being built. No major delays are expected as the temporary paved detour road, operational in October 2012, will remain mostly open to two way traffic with occasional single lane alternating.
As we construct the detour road and overpass, there will be reduced speed limits posted throughout the construction zone. This allows us to maintain all local accesses and existing traffic movements.
Key construction work includes clearing and grading the area, building a temporary paved detour road, constructing abutments and an overpass span as well as numerous utility relocations. One visible component of construction will be the stockpiles of large white expanded polystyrene (EPS) blocks that will be used in the overpass ramps.
As of October 2012, nearby residents may notice noise from repetitive hammering as the abutments for the overpass is built. However, these effects are temporary in nature and BA Blacktop will monitor noise and vibration throughout the pile driving activity.
We apologize in advance for any inconvenience and thank you for your understanding.
Traffic advisories will be issued to notify of any upcoming major changes to traffic patterns. They can be found online here, at www.robertsbankrailcorridor.ca, or email us to join our mailing list (please add ‘232nd St’ in the subject line).
