Piles of logs have been put next to the Penwortham Bypass.
Lancashire County Council say they are there to help encourage amphibians, insects and other small animals.
The multi-million pound road will link the A59 and the A582.
Cabinet member for highways and transport county councillor Keith Iddon said: “We recognise that while the road is needed to reduce congestion through Penwortham, it will disrupt some wildlife. So we’re putting some measures in place to help them, such as these log piles.
“Lots of progress is being made to create the new road, which opens early next year. Along the A59 Liverpool we’re currently creating the new junction with the bypass. Thank you to people for their patience while the construction work is taking place, especially for any disruption it has caused to your journeys in this area.”

Further log piles are expected to be added as construction work continues into early 2020.
Cabinet member for planning, regeneration and ciy deal at South Ribble Borough Council councillor Bill Evans said: “It is good to see the work on the Penwortham Bypass progressing well as it will help the traffic flow in Penwortham and South Ribble.
“The creation of log piles to create a new habitat for insects and small animals alongside the new road is important, as it will help to minimise the impact on local wildlife.”
