Steelwork for road infrastructure

Road and motorway gantries

C.M. Costruzioni S.r.l. designs, manufactures and maintains gantries, poles and steel structures for signage, monitoring and traffic information. The structures support variable message signs, cameras, sensors and ANPR devices for smart road infrastructure.

Cantilever gantry

Single-arm steel structure, with material and finish specified for each project, designed to cantilever over the carriageway and support:

Variable message signs (VMS)
Video surveillance systems
Sensors and ANPR devices

Customisation and testing

Made to dimensions tailored to the client’s requirements, with provision for internal cabling and simplified maintenance.

Each gantry undergoes load testing and is supplied ready for transport, in compliance with applicable standards.

Integrated raising and lowering systems for speed cameras

Steelwork structure fixed to a motorway gantry, with a vertically moving carriage operated by a mechanical winch, designed to position the electronic equipment for the average-speed monitoring system. Equipment can be installed and maintained directly from the gantry walkway, providing straightforward access.
