Over 300 new trees, 10,000 smaller shrubs and plants and an extensive new drainage system are just some of the ways county engineers are lessening the new road's impact on local ecology.
Cllr Richard Davies, executive member for highways, said: "Protecting local ecology and wildlife is a very important part of every big road project we undertake across the county.
"That’s why an ecological survey is always one of the first pieces of work we carry out, since it outlines how our plans could impact nature in the area and provides us with guidance on how to minimise the impact of our works.
"Because the Lincoln Eastern Bypass is such a massive scheme that is being built over a quarry, river and other types of terrain, we've worked hard to face the challenges in a way that ensures we have as little impact on local wildlife and its natural habitats as possible."
Below are some of the ecological challenges the team has faced while building the new bypass:
Nesting birds
Adam Round, principal engineer for the bypass scheme, said: "We've encountered nesting birds several times, most recently at the temporary haul bridge over the River Witham.
"Each time this happened, we worked closely with Galliford Try to manage the timing of our activities to avoid disturbing the nests, while also ensuring there was no impact on the project's schedule.
"For the haul bridge, we left it up for an extra six weeks until the fledglings left the nest and we were finally able to dismantle and remove it."
Flooding and drainage
Adam Round said: "Lincolnshire experienced more than twice its average amount of rainfall in September and October 2019, along with several other periods of really wet weather throughout the construction.
"As a result, we had to install extra temporary drainage and additional water pumping to compensate. Despite this, the ground was completely saturated for months so we used lime to stabilise it so we could move and use the earth elsewhere.
"Working with the Canal & River Trust, we've also dredged where the bypass crosses the River Witham to lessen the impact of future flooding and have installed an extensive drainage system across the entire bypass route.
"This includes six detention ponds that will help remove contaminants and slow down the water flow into the river and other nearby watercourses."
Greetwell quarry
Adam Round said: "The new bypass will cross over of a section of Greetwell quarry, which is home to varied local wildlife, including birds and bats. With this in mind, we've limited works in the area to a very strict space to avoid disturbing this habitat.
"We're also installing bat boxes on the boundary of our works and are landscaping the area between the quarry and the new road so that wildlife here can continue thriving."
As part of the project, 20 bat boxes will be installed across the site, including at Greetwell quarry and near the River Witham. Badger fencing and two badger underpasses will also be installed just north of the River Witham.
Cllr Davies continued: "To ensure Lincoln's local wildlife has an environment where it can continue living and thriving for years to come, we've also built a new wildlife pond just north of Greetwell Road.
"The pond and its surrounding woodland area are the size of fourteen tennis courts and will be home to a variety native wildlife, from birds and newts to moorhens and bats.
"In total, we're planting 305 new trees throughout the bypass site, along with over 10,000 smaller shrubs and plants, 68,000 hedge plants and wildflower areas totalling the size of three football pitches.
"We've also used earthwork bunds to help lessen the visual and noise impact of the road.
"This, combined with all of the planting we've done, will ensure that Lincoln's local wildlife has an environment where it can continue living and thriving for years to come."
The new Lincoln Eastern Bypass is set to open by the end of the year, with a date set to be announced in the coming weeks.
