The M11 between Stansted and Harlow has now completely re-opened following a chemical spill last night which closed the road since 5pm Thursday.
The road is now open between junction 7 and 8.
Operations Manager for the Highways Agency Caner Okanay said. "The nature of the chemical involved meant that we had to ensure none of it reached the water course. This meant we had to jet wash the carriageway. We would like to thank drivers for their patience last night and this morning."
The Highways Agency is now estimating that the M11 between Junction 8 and junction 7 will completely re-open at 10.45am.
The road between Stansted and Harlow has been shut southbound since 5pm Thursday evening after a chemical spill.
The M11 southbound entry slip road at Junction 8 remains closed at the moment.
The Highways Agency says it hopes the M11 between Stansted and Harlow will re-open by 9am on Friday.
The road has been closed since about 5pm on Thursday when a lorry overturned spilling chemicals.
The northbound carriageway opened at 5.50am on Friday but the southbound stretch was still closed during Friday's rush hour.
The road surface was covered with a chemical foam and at one point firefighters had to impose a 150 metre exclusion zone.
“The nature of the chemical involved has meant that we have had to ensure none of it reaches the water course and so the clean up operation involves jetwashing the carriageway surface and then using gulley suckers to ensure all liquid is removed and can be safely and environmentally disposed of away from the scene."
The M11 motorway in Essex is still closed southbound after a lorry overturned and spilled chemicals across both carriageways during Thursday evening's rush hour.
The HGV was recovered overnight but the Highways Agency says a "complex and specialised clean-up operation continues."
There is a diversion in place with southbound vehicles leaving the M11 at junction 8 at Stansted. They are directed along the A120 westbound towards Puckeridge and then the A10 southbound and the A141 towards Harlow where they can re-join the M11 at junction 7.
Drivers should allow extra time for their journeys. The Highways Agency hopes the road will be re-open by 9am. The northbound carriagway opened at 5.50am.
