I-95 (Section 100) Express Toll Lanes I-895 to South Kenwood/Chesaco Avenue Bridges
Baltimore County, MD

Maryland Transportation Authority

Cherry Hill Contract Value:
$95.68 million

Project Description:
This “Award Winning” project consisted of extensive highway widening of a section of I-95, in order to provide two Express Toll Lanes (ETL) in each direction.  Cherry Hill Construction, Inc. (CHC) was the Lead Contractor providing construction services on this $95.6M project extending 1.8 miles from the I-895 split to south of the Kenwood Avenue Bridge in Baltimore County.  The ETL section consists of a 12’ outside shoulder, two 12’ lanes and a 4’ inside shoulder with permanent concrete traffic barrier.  The structural elements of this project included the phased support and extension of the Chesaco Avenue Bridge over I-95, soil nail walls at both the Chesaco and Hazelwood Avenue existing structures and 8 retaining walls and 9 Noise Abatement Walls in order to reduce impact to adjoining properties and stay within the existing right-of-way.  Two controlled access points (using electronic gates) to I-95 were provided for emergency vehicles including an on-bound ramp.

Major Items of Work included:
  • Multi-phased MOT to allow continuous traffic on I-95 (ADT of over 178,000) during construction of four new and 8 reconstructed through traffic lanes on I-95 as well as Chesaco Ave during bridge construction.
  • Over 320,000 CY of excavation and 35,000 CY of borrow.
