PennDOT Highlights 2019 Construction Season in South Central PA

Approximately 170 construction projects were active and 76 were completed in the PennDOT Engineering District 8 region covering Adams, Cumberland, Dauphin, Franklin, Lancaster, Lebanon, Perry, and York counties last year.

In addition to those projects, bids were opened for 66 contracts totaling nearly $211.8 million in value. Included in the contracts awarded in 2019, some of which are multi-year projects, was a new Diverging Diamond Interchange (DDI) project aimed at improving safety and traffic operations at Route 222 and Route 322 near Ephrata, Lancaster County. This is the second DDI project in District 8 and only the third such interchange in the state. A DDI project currently is underway on Interstate 83, Exit 4 (Shrewsbury), in York County. This project began in spring 2019 and is expected to be completed in spring 2021.

In addition to work through contracts, resources were further maximized with department forces completing more than 75 miles of paving and 175 miles of seal coating (oil and chip) in 2019. District 8 department forces also placed more than 5,500 tons of Recycled Asphalt Paving, or RAP, which repurposes materials from projects onto other roadways by mixing ground millings with oil.

“Using recycled asphalt pavement is an innovative, environmentally friendly method of maintaining our low-volume roads,” said District 8 Executive Michael Keiser, P.E. “This process reduces the amount of asphalt that ends up in landfills and can be done by department-force crews.”

Work was performed on 57 state-owned bridges by contractors or department forces. This included the replacement or rehabilitation of 25 bridges, and preservation work on 25 bridges to extend the life of those bridges.

There were seven small bridge projects completed by department force crews. This included a bridge rehabilitation project completed by the Adams County Maintenance organization on Route 4004 (Quaker Valley Road) near Biglerville, for which the concrete bridge deck slabs for the project were fabricated at the county maintenance facility. Having the capability to cast bridge decks allows small department force bridge projects to be completed in a less costly and more efficient manner.
