Structural steelwork contractor Britcon positioned the bridge over the River Witham in front of a crowd of spectators last week and has now completed its £850,000 contract for Lincolnshire County Council.
The new bridge replaces the former 1970s’ structure.
Crane hire firm Baldwins supplied a 500-tonne capacity all terrain crane to lift out the old bridge and a 1,000-tonne rated crane to lift in the new.
Britcon project manager Andy Newell said: “We hosted a number of workshops to finalise the design details and resolve the many issues of building a bridge on such a confined site.”
He added: “The new structure is wider than the existing bridge and has an elliptical deck allowing people to admire the nearby Boston Stump without obstructing the crossing. Key features include a non-slip surface and improved access for pedestrians, wheelchair users, dismounted cyclists, pushchairs and mobility scooters.
“The bridge also colour matches the yellow lighting of the octagonal lantern in the church tower, which is believed to have been used as a marker to guide travellers on land and sea. There is also a tri floral motif installed into the parapet which will replicate the nearby Town Bridge.”
Britcon constructed a mini anchor piling system to avoid vibration adjacent to nearby properties. Laboratory testing was also undertaken to provide ground information to aid the foundation design.
