Emergency services were called to a collision this morning (Wednesday) which closed the slip road off the A17 onto the A153 Ruskington Road outside Sleaford.
A police spokesman said the incident happened just after 8.30am opposite the rugby club and involved a Renault lorry from Newark and a woman in a silver MG car from Grantham.
The woman was taken to hospital with a back injury but no life threatening injuries while the lorry driver was unhurt.
The collision left the vehicles in the middle of the road and the slip was closed to allow emergency services to clear the scene.
The road was still blocked according to the last report at 9.08am, causing disruption to motorists diverted heading to work and school. The west bound slip road on the opposite side of the A17 is still open.
