An offset T-intersectioncite-ref-1[1] is an at-grade road intersection where a conventional four leg intersection is split into two three-leg T-intersections to reduce the number of conflicts and improve traffic flow.cite-ref-2[2] Building the offset T-intersections as continuous green T-intersections (also called seagull intersection), there is a single stop on the arterial road, only.cite-ref-trb650-3-0[3] A higher volume of through traffic on the cross road,cite-ref-4[4] or on unsignalized intersections, a rebuild to a conventional four-leg intersection may be adequate, also when the offset is a few feet only like staggered junctions causing slower traffic for a longer time on the arterial road.cite-ref-5[5]

Seen as a spur route or access road, offset T-intersections can be seen as an A2 or B2 type partial cloverleaf interchange with no arterial road.cite-ref-kit-eub-se-2013-6-0[6]
