Opposition from MP John Hayes, the parish council and 49 villagers failed to derail an outline planning application for 38 homes to be built on Milestone Lane, Pinchbeck.
Most objections centred on highway safety because of narrow lanes and lack of footpaths, but there were also concerns about increased noise and added pressure on doctors, dentists and schools.
Lincolnshire County Council, the highways authority, raised no objection subject to applicants Mr and Mrs R Hart widening Milestone Lane to five metres and adding a path and street lights between the site entrance and its junction with Crossgate Lane and creating a pedestrian link within the site to Gallery Walk.
Resident Terry Moore told the planning committee that the proposed conditions didn’t go far enough to address highway safety concerns.
He said: “With increased traffic, and the lack of passing places on the road, we believe this network is unsustainable.”
Planning committee member Coun Pete Williams said he accepts narrow roads can be a problem but a lot of the time they stop people driving so fast.
