DOTs and railroads rarely allow a road or track to be cut open for a utility line. GriffinCo bores under them instead, so traffic and trains keep moving while the line goes in below.
We work for utility owners, general contractors, and road builders on crossings across coastal Alabama, Mississippi, and Florida.
Crossings We Install
- State highway and interstate crossings
- County and city road crossings
- Railroad crossings with steel casing
- Driveway, parking lot, and intersection bores
Why Trenchless for Crossings
- No lane closures for the bore. Traffic keeps moving overhead.
- Meets DOT and railroad requirements. Cased, on-grade crossings that pass review.
- No pavement restoration. The road surface is never cut.
Methods We Use for Crossings
- Auger Boring (Jack & Bore): the standard for cased road and rail crossings.
- Horizontal Directional Drilling (HDD): longer crossings and multi-lane highways.
- Microtunneling: gravity lines that must hold exact grade under the road.
