The B1189 is a rural B-road on the edge of the Lincolnshire Fens.
It starts on the A153 on the eastern edge of Billinghay and heads west, crossing the Billinghay Skirth before going through the village. It goes through Walcott and bypasses Timberland before meeting the B1191, which multiplexes with it for about half a mile. The B1189 then crosses the former RAF Metheringham, which was closed soon after World War II. Its runways can still be made out from the air; one, the next road to the right signposted Blankney Fen, has now become a minor road.
The B1189 turns westwards to enter Metheringham itself. It crosses the Lincoln to Sleaford railway line at a level crossing by the station before zigzagging through the village and ending on the B1188.
