Resource Access Bridges
Resource Access Bridges
Single-lane modular bridges are portable bridge superstructures designed for ease of installation and use on low-volume roads. The heavy-duty design is built with safety in mind and consists of two separate sections featuring four girders each for a total of eight girders per bridge.
Single lane stringer bridges are designed for full highway loading on low volumes roads and permanent bridge solutions.
These bridges are critical assets for the forestry, mining and resource management sectors as their durable design is easy to transport and install while providing safe, reliable access to remote areas. Resource access bridges are also an economical solution for Cottage Associations, OFSC members, or private homeowners to gain safe, reliable access to their properties.
With multiple bridge lengths available and a low structure profile, resource access bridges also have a high-performance coating and anti-slip surface making them an incredibly safe option.

Resource Access Bridge Features
Tapered Or Square Ends
Our access bridges are manufactured with a tapered or square end at no additional cost. Tapered-end bridges are excellent for use in locations where the bridge is installed on a substructure that does not have an upper approach crib leading to the deck.
Steel Checker Plate Decking
Access bridges are shipped complete with a 3/8″ pre-welded steel checker plate deck. Compared to a timber deck, a steel deck offers significant savings in maintenance including labour and wood, over the life cycle of the bridge.
High-Performance Coating And Anti-Slip Surface
To ensure proper adhesion of paint and non-slip coatings, all main stringer beams are cleaned and shot blasted in accordance with SSPC-SP 6 industry standards.
A high-performance red oxide primer is then applied to the entire structure and as part of the painting process, a dense grit product is added to prevent workers from slipping or falling during construction.
Decking Access Points And Weighted Cover Plates
Access points or “cutouts” in the surface of the decking allow installers to bolt both sections together. Weighted cover plates are then provided to ensure all openings are covered and the deck surface remains level and flush.
Pulling and Lifting Lugs
There are three pulling lugs pre-welded to the ends of each section for a total of twelve. These lugs are reinforced to provide safe lifting and pulling locations for easy bridge installation.
Tie-Downs and Tie-Down Guides
Modular bridge sections are linked by tie downs, strategically positioned along the centerline, and facilitated by tie-down guides. These guides, welded in place, ensure quick and precise alignment for connecting adjacent sections, with assembly bolts securing the junction.
Nut Locking Bars
Bridge bolts securely fasten to tie downs, with nut locking bars beneath ensuring a ‘snug + 1 turn’ position from the top of the deck. The alignment of tie downs and guides is precise, as modular bridge sections are fabricated side by side in the shop.
Structural Grade Bridge Assembly Bolts
Structural grade bridge assembly bolts are included with every bridge. It’s recommended to apply light oil or a product like “Never Seize” during installation for optimal long-term maintenance.
Bolted Post Pockets
Bolted post pockets, assembled in the field, enhance the performance and maintenance of guardrail installations. These pockets meet the anchoring requirements of the TL1 Barrier standard, as specified in the MTO 2016 “Exceptions To The Canadian Highway Bridge Design Code CSA S6-19, For Ontario.”
