Lincoln MP Karl McCartney has warned that the Southern Relief Road, which would complete the ring road around the city, needs to be completed urgently to avoid congestion.
Mr McCartney said he expressed his concerns during meetings with numerous transport and local government ministers in September.
The southern part of the bypass is known as the Southern Relief Road, and is the final outstanding section of the project to be completed.
McCartney said: “Any delay in the completion of the Southern Relief Road, the ‘5-7pm section’ of the city’s Eastern Bypass, being built will negatively affect a huge swathe of Greater Lincoln residents who live in the commuter areas of North Hykeham, Waddington and Bracebridge Heath.
“It will also affect those drivers who use the incomplete Eastern Bypass and find themselves using residential roads to find and reach the A46 or to travel particularly north to south and vice-versa.
“I have particular concerns with the increased traffic flow in the village of Waddington and all over the South of Lincoln, namely along Brant Road, Station Road and Grantham Road.
“The building of the complete Eastern Bypass will help ease some of these issues, hence the need for it as soon as possible, and why I have campaigned for it since 2004.”
Dr Caroline Johnson, the Sleaford and North Hykeham MP, has also been campaigning on the issue recently.
Meanwhile, the Lincoln Eastern Bypass is taking shape, ready for the end of the year.
