The section of Old County Road in Rockland closed since Feb. 15 due to a massive sinkhole should be open for vehicle traffic by Wednesday, April 7.

Maine Department of Transportation Regional Engineer Jamie Andrews said heavy rains have slowed the repair work but he expects the road will be open on Wednesday, April 7.

Paving and installation of guardrails along that curved stretch of road will not be done until mid to late April, Andrews said.

The state has been working at the site since March 15 and creating a slope from the adjacent state-owned quarry to the roadway, replacing what had been a sheer cliff with a tunnel under the road. Materials have come from Dragon Products.

The project was estimated to cost $250,000 and is being paid for by the state.
