Berkeley Heights interchange project subject of public meeting
Staff Report


BERKELEY HEIGHTS -- The public -- and local residents in particular -- are encouraged to attend Wednesday's public information meeting concerning a proposed $25 million construction project aimed at correcting the Diamond Hill Road interchange,which is plagued by illegal turns and traffic congestion.

A New Jersey Department of Transportation representative and a consultant will be at Wednesday's meeting -- scheduled from 3 to 7 p.m. in township council chambers at 29 Park Ave. -- to gather resident and driver input about the partial interchange. The state representatives will have design plans for the proposed project, which is federally funded and expected to begin in December 2007 and continue until March 2010.

Drivers traveling on Interstate 78 West, heading toward Route 22, use the westbound off-ramp at Exit 43 and then make an illegal left turn onto Diamond Hill Road southbound. Other drivers exit from the ramp and then use Ghost Pony Road, the Diamond Hill Community Church or McMane Avenue as a U-turn to access Diamond Hill Road southbound. Some northbound drivers on Diamond Hill Road make an illegal turn onto the ramp to I-78 westbound.

Additionally, drivers heading toward Route 22 or the Scotch Plains area use Exit 41 further to the west in Berkeley Heights. During peak traffic, the volume of traffic exiting often causes queues onto the deceleration lane or shoulder of westbound I-78. According to the state transportation department, the proposed project has several components, including constructing a new loop ramp to accommodate northbound Diamond Hill Road traffic to westbound I-78.

In addition, a new ramp would be constructed from the new westbound off ramp that curves to the south and passes under Diamond Hill Road before merging into southbound Diamond Hill Road near an I-78 bridge.

Diamond Hill Road southbound would be widened from this point through the Twin Falls Road intersection.

Northbound Diamond Hill traffic would be reduced to one lane between the new westbound on-ramp and the westbound off-ramp.

Other project improvements involving bridge widenings and retaining walls would also result.
