WILTON \u2014 A northbound lane on Scribner Hill Road is likely to be closed until an engineer can address the steep slope. Department of Public Works Director Frank Smeriglio is reviewing bids for a geotechnical engineer to address a shift in the street slope on a stretch of Scribner Hill Road that has been closed since last week. Smeriglio cited a \u201csteep slope on one side of the road\u201d as the cause for the closure of the northbound lane. Since the shift was noticed, the town has put stop signs on both entry points and created a one-lane road. Although he couldn\u2019t give a definitive timetable, Smeriglio said it is likely \u201cgoing to be a while\u201d before the road is back to being fully open. \u201cThe way it sloped,\u201d he said Wednesday, \u201cwas a cause of concern.\u201d An initial notice from his department last week said the road conditions will be monitored \u201con a daily basis.\u201d At this point, Smeriglio said he isn\u2019t fully certain of the cause, but carefully surmised that entrapped water under the pavement could be playing a role. The goal is to stabilize the slope. For that, he said the town will need to hire a geotechnical company to assess and ultimately fix the damages. He is in the bid review process and will need to make a recommendation for approval to the first selectwoman for the project to move forward. Scribner Hill Road features a guardrail running along the affected northbound lane due to the \u201csteep edge\u201d that Smeriglio said will play a factor into the geotechnical boring process once a bid is recommended and approved by the town. While he did not have the traffic count for the stretch of road, Scribner Hill also acts as the connecting artery between Mountain Road and Danbury Road.
