Abstract

The invention relates to a road gantry comprising a horizontal beam (2), the upper surface (21) of which constitutes a passageway for service personnel to cross, the gantry being characterized in that it comprises arms (25) for bearing apparatuses (30) for monitoring road traffic, electronic toll collection, or signaling, wherein said arms are pivotably attached to the horizontal beam so as to be able to move from a first position, in which the arms extend towards the road, into a second position for stowage on said passageway, and vice versa. The passageway may comprise protection guardrails (22, 23) in which openings (24) are formed, said openings being shut by door panels (24) arranged so as to enable the passage of said arms (25) from said first position to said second position and vice versa. The invention also relates to a barrier-free electronic toll collection station including at least one such gantry.

Claims
