Roads and railways can't be cut — they have to be crossed. Apex specializes in long-distance HDD crossings for highway underpasses, arterial roads, and active rail corridors, with bores up to 500 feet.
Real numbers from our Vermeer D20x22 S3 and field experience on road and railway crossing projects.
Every crossing type has different permit, depth, and casing requirements. We know them all.
Long bores under state highways, county roads, and city arterials — Caltrans and local encroachment permits coordinated. Minimum depth and casing requirements met.
Encroachment PermitBores under active rail corridors — Union Pacific, UPRR, Caltrain. Railroad license agreement coordination and minimum cover depth compliance.
Active Rail CorridorsPull multiple utilities through a single casing bore — gas, electric, water, and fiber in one crossing saves permitting cost and future pavement damage.
Bundled Crossings8" and larger water main crossings under roads and highways — HDPE or steel casing with product pipe pulled through.
Up to 8" DiameterOQ-certified gas line crossings under roads — from 2" service laterals to larger distribution main crossings, all per PG&E and local gas district requirements.
OQ CertifiedLong bore conduit crossings for electrical transmission, fiber backbone, and telecom infrastructure under roads and active rail.
Telecom & ElectricOur Vermeer D20x22 S3 handles bores up to 500 feet — covering most road and railway crossing widths in the Bay Area.
We work with Caltrans, county roads, city engineering, and railroad right-of-way departments to get encroachment permits done right.
HDD eliminates lane closures in most cases — critical for highways and arterials where traffic control costs can exceed the bore cost itself.
Gas crossings under roads require OQ-certified crews. We're qualified and current — no delays bringing in a specialty sub.
We know the cobble, rock, and mixed soil conditions common in Bay Area road crossing projects — we plan for it, not around it.
B General, A General Engineering, and Hazmat licenses cover the full scope of road and rail crossing work including contaminated soil.
