EBL automates three views per bridge project. Pick the one you need or get the full package.

All measurements: feet, decimal, US imperial only — no metric.

View 1 — General Layout

Plan view

The General Layout is the plan-view drawing of the bridge — looking straight down at the deck, approach slabs, wing walls, and abutments. It captures the footprint of the structure: overall length and width, support skew, and the geometry of the wings and abutment notches.

Inputs collected

Plan

—Total Length
—Deck Width
—Support Skew

Approach slab

—Slab Length

Wing wall

—Thickness (W)
—Length (L) from abutment back face
—Inwing to Deck

Abutment

—Notch Length
—Width (W)
—Corner Notch

What you receive

—Layout.txt — A .txt script with the View 1 geometric line work, ready to load into AutoCAD or MicroStation.
—Delivered by end of next business day.
—Compatible with AutoCAD and MicroStation.

View 2 — Deck Layout

Deck cross section

The Deck Layout is the cross-sectional view of the bridge deck — cut perpendicular to the bridge centerline. It shows the deck slab thickness, haunch, beam spacing and overhangs, and the cross slope on either side of the centerline.

Inputs collected

Deck geometry

—Width (between outside edges)
—Thickness
—Haunch at CL of bearings

Cross slope

—Left of CL (negative if CCW)
—Right of CL (negative if CW)

Beam layout

—Number of Beam Spaces
—Clear Deck Overhang
—Width of Beam Top Flange
—Deck Exterior Flange Cover

What you receive

—Deck.txt — A .txt script with the View 2 geometric line work, ready to load into AutoCAD or MicroStation.
—Delivered by end of next business day.
—Compatible with AutoCAD and MicroStation.

View 3 — Bridge Elevation

Side elevation

The Bridge Elevation is the side view of the bridge — showing the abutments, piers, approach slabs, and the span geometry between supports. It captures the vertical dimensions: girder depth, cap dimensions, bearing seats, and how the spans add up across the length of the bridge.

Inputs collected

Abutment

—Front Face to CL of Bearing
—Cap Width
—Depth Below Bearing Seat
—Depth Bearing Seat to Top of Slab
—Girder Depth

Approach slab

—Slab Length
—Notch Length
—Notch Depth

Pier

—Front Face to CL of Bearing
—Cap Horizontal Width
—Cap Vertical Depth

Geometry

—Skew (absolute degrees)
—Beam Extension Length

Spans

—Dynamic span list (minimum 1, no maximum)

What you receive

—Elevation.txt — A .txt script with the View 3 geometric line work, ready to load into AutoCAD or MicroStation.
—Delivered by end of next business day.
—Compatible with AutoCAD and MicroStation.
