Baltimore County, MD
Maryland Transportation AuthorityCherry Hill Contract Value:
$95.68 millionProject 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.

- Constructed two new stormwater management facilities.
- Reconstructed I-95 NB and SB and new ETL required over 190,000 TNs of asphalt superpave.
- 187,500 TNs of 6” graded aggregate base and 53,326 SY of cement stabilized soils.
- Removed over 19,600 LF of existing concrete traffic barrier and installed approx. 40,967 LF of new 34” and 42” F shape concrete traffic barrier.
