A PAINT spillage has turned the morning rush hour into a crawl on the A3(M) south of Horndean.
Long queues are developing on the northbound carriageway as overnight roadworks have overrun.
One lane at Junction 2 Horndean has been closed for safety reasons, causing tailbacks to the Purbrook and Leigh Park exit.
Highways England have confirmed within the last hour that both lanes of the northbound carriageway at the same junction will be closed from 10am this morning for emergency resurfacing.
Traffic will be diverted via the exit and entry slip roads at the junction, with repairs likely to be completed by lunchtime.
Motorists heading from the Portsmouth area to Petersfield and London have been urged to allow extra time for their journey as a result.
