MONTPELIER – On Thursday, July 15 the Vermont Agency of Transportation (VTrans) will conduct ledge removal that at times will cause delays along Interstate 89 just south of Exit 8 in Montpelier.
VTrans routinely inspects rock ledge that borders Vermont’s Interstate and state roadways. Geologists recently concluded that ledge about a half mile south of Exit 8 along I-89’s northbound barrel is fragile and must be removed before rocks break loose and fall into the roadway.
To remove the loose ledge, VTrans on July 15 will close one lane of I-89’s northbound barrel so workers can safely access the ledge. Also, between the hours on 9 a.m. and 3 p.m. VTrans in conjunction with the Vermont State Police will delay northbound traffic along I-89 between Exit 6 (South Barre) and Exit 7 (Berlin) using a series of rolling road blocks. The rolling roadblocks, which could last up to 10 minutes, will be conducted whenever crews must allow ledge to drop so that no vehicles are impacted.
Police during a rolling roadblock will use their vehicles to slow traffic to about 45 mph so that it will take about 8 minutes to travel between Exits 6 and 7. Although police hope to keep traffic moving, there is the potential that at times traffic will need to be stopped completely.
Once the ledge falls and all debris is cleared, traffic will be allowed to resume. VTrans expects there will be need for about a half dozen rolling roadblocks between the hours of 9 a.m. and 3 p.m. The roadblocks will occur when needed, so no exact schedule is known. Police will also close the Exit 7 onramp to I-89 northbound whenever rolling roadblocks are in effect.
The southbound lanes of I-89 will not be impacted by this ledge work.
