[p. 83] the stone abutments or walls recently built, from North to South the whole length being about sixty five feet, and width about thirty eight feet, with a draw in the place, where the present draw is placed, the said draw to be made of two leaves,—and the width from east to west, Thirty feet, and from North to South Twenty nine feet, leaving thereby a passageway for vessels of twenty nine feet, and furnished with Machinery, and Iron chains to raise it, in all respects equally sufficient for the purpose, as the draw now is on Warren Bridge at Charlestown.
The said Bridge is to rest on the Stone Abutments on each side, and on white oak piles to be driven into the ground at proper distances, so as to form the passageway for vessels.
The said piles to be at least thirteen inches square at the top, with white oak caps in proportion.
The string timbers of the Bridge parts to be six & a half inches wide, & thirteen inches deep,— and those of the draw to be at least sixteen inches at the ballast end and seven by ten inches at the ends where the leaves meet, with proper and sufficient white oak caps,—the piles to be braced as they are done at Warren Bridge.
The wheels of the draw machinery to be of the same kind of wood with iron cog rings, and the draw to be balanced with iron ballast in like manner.
The whole to be planked with good pine plank free of sap, three inches in thickness, and sheathed with spruce plank of two inches in thickness.
A single railing is to be made the whole length of the bridge on both sides, and an inside railing to guard foot passengers as far as the draw.
And the said Samuel Chittenden has agreed and does hereby agree to build a Bridge as above described & with good and sufficient materials, in every respect sound and strong, & with like machinery as now in use at Warren Bridge, to the acceptance of said committee, the whole to be completed within the term of forty days, and the work to be done without any obstruction to the public travel, in so far as the west part of the Bridge
