Bentley OpenBridge Designer
MicroStation-based bridge design and analysis application for concrete and steel bridge modeling, analysis, design, and load-rating -- integrates terrain, roadway geometry, access ramps, and related infrastructure assets, with support for AASHTO LRFD/LFD/LRFR and international bridge design codes.
Made by Bentley Systems, public (BSY, $10.1B)
2.8 /5 composite score
Situational -- a comprehensive bridge information modeling (BrIM) environment with published pricing ($10,028/yr via Virtuosity) and iTwin Platform REST API access, but the MicroStation dependency, enterprise pricing, and DOT-scale learning curve limit it to large infrastructure practices already in the Bentley ecosystem.

Alternatives in Civil & Infrastructure Design
AutoCAD-based civil engineering design and documentation platform for grading/surfaces, road and rail corridor modeling, pipe network hydraulics, and survey -- the civil-engineering flagship that turns conceptual InfraWorks models into construction-ready plan/profile sheets and quantity takeoffs.
3.4/5
Free, public-domain stormwater, wastewater, and combined sewer system simulation model by the US Environmental Protection Agency -- dynamic hydrology-hydraulic-water quality simulation for single-event or continuous modeling of rainfall-runoff, pipe/channel routing, green infrastructure/LID controls, and pollutant loads; the industry-standard computational engine used worldwide for drainage design, CSO/SSO mitigation, floodplain mapping, and regulatory compliance (NPDES, CMOM, TMDL).
3.4/5
Free, public-domain water distribution system modeling software by the US Environmental Protection Agency -- performs extended-period simulation of hydraulic and water-quality behavior within pressurized pipe networks (pipes, pumps, valves, tanks), tracking flow, pressure, water age, chlorine residuals, and contaminant transport; provides a C Programmer's Toolkit (DLL with 50+ functions) for custom integration; the industry-standard computational engine underlying most commercial water-distribution modeling packages worldwide.
3.4/5
Early-stage conceptual infrastructure design tool that builds a GIS-rich 3D context model (terrain, imagery, existing utilities) for rapid road, bridge, rail, and drainage concept design and stakeholder visualization before detailed design moves into Civil 3D or Revit.
