UPDATE: A blockage on at the Chapel St On Ramp is now clear, but motorists are warned to expect delays until the congestion clears.
Tauranga City Council says traffic can now move up onto the SH2 Harbour Bridge system.
"There is significant local congestion which will take some time to clear.
"This congestion will still take some time to clear so delays can still be expected for some time."
People travelling between Tauranga and Mount Maunganui via the Chapel Street On Ramp are being asked to avoid the area this morning.
There is a blockage on the Chapel St On Ramp to the Harbour Bridge due to a caravan that has broken a draw bar, says a Tauranga City Council spokesperson.
"The on ramp is completely blocked."
Council reports there is major congestion and traffic is backed up on Chapel St and Ngatai Rd, past Bureta Rd.
"Expect significant delays.
"Consider delaying travel or using alternate routes."
