A gangway comprising a proximal gangway member and a distal gangway member inserted into the proximal gangway member and slidable in a telescopic manner relative thereto, between a retracted terminal position and an extended terminal position, a distal stanchion hinged at a distal end of the distal gangway member, and a distal stanchion control mechanism comprising a distal rod having a distal end articulated to the distal stanchion and a proximal end provided with a block, and a distal rod abutment integral with the proximal gangway member and configured to be engaged by the block of the distal rod, wherein the extraction motion of the distal gangway member comprises a first motion phase, in which the distal rod is driven by the distal gangway member until the block of the distal rod is abutted against the distal rod abutment, and a second motion phase, in which the distal gangway member moves relative to the distal rod abutted against the distal rod abutment and the distal stanchion is rotated from a lying position to an upright position by means of the articulation with the distal rod, said gangway being characterized by further comprising a proximal stanchion hinged at a proximal end of the proximal gangway member, a proximal stanchion control mechanism, comprising a proximal rod having a proximal end articulated to the proximal stanchion and a distal end provided with a block, and a proximal rod abutment integral with the distal gangway member and configured to engage the block of the proximal rod, wherein in the first motion phase the distal rod is driven by the distal gangway member until the block of the distal rod is abutted against the distal rod abutment and the proximal rod abutment is abutted against the block of the proximal rod, and in the second motion phase the distal gangway member moves relative to the distal rod abutted against the distal rod abutment and the distal stanchion is rotated from a lying position to an upright position by means of the articulation with the distal rod, while the distal gangway member drives the proximal rod by means of the proximal rod abutment and the proximal stanchion is rotated from a lying position to an upright position by means of the articulation with the proximal rod, wherein said stanchions (12, 22) are at least partially tubular, said gangway further comprising an extensible elastic rope by means of which the stanchions (12, 22) are connected to each other, said elastic rope acting as a handrail when the stanchions (12, 22) are in the upright position and being arranged in such a way that, in the lying position of the stanchions (12, 22), excess rope is collected within the stanchions. a proximal gangway member and a distal gangway member inserted into the proximal
