A burst water main closed the A158 in both directions this morning, Friday February 24.
The road was shut due to flooding on Skegness Road between Lincoln Road in Skegness and Middlemarsh Road.
It has now reopened, but traffic lights are controlling the flow while Anglian Water engineers work to repair the main.
The 10-inch main has burst near Southview Leisure Park and engineers say it is the primary water main into Skegness.
Stagecoach bus services 6 and 6a are not serving Southview Park as a result.
