Pier construction underway at 301/304
CENTREVILLE — With a critical stream relocation under US 301 (Blue Star Memorial Highway) nearly complete, the MD 304 (Ruthsburg Road) interchange project has quickly begun to rise above the existing road grade.
The Maryland Department of Transportation’s State Highway Administration is working on fill operations on both sides of US 301. The fill areas will eventually provide the base for two roundabouts and associated ramps.
In the US 301 median, preparations are underway for a pier that will support the new interchange overpass.
“Once the drainage pieces are in place, we can push ahead with the extensive fill and grading work — this area will be elevated about 20 feet as part of the approach to the new bridge over US 301,” said Bob Rager, SHA district community liasion. “In the next few days, you’ll see pile driving in the US 301 median followed by formwork and pouring of the large median pier that will carry the new overpass.”
To provide a safe buffer for pile driving and bridge pier construction, SHA closed the left turn lane from southbound US 301 to eastbound MD 304. Additionally, the US 301 northbound left through lane is closed at the work area. The left turn lane from northbound US 301 to westbound MD 304 was previously closed in conjunction with the closure of MD 304 at Tidewater Drive. Motorists can use existing J-turns along US 301 to change direction and access MD 304 east of US 301.
SHA expects that the median pier should be completed by late summer, weather permitting. The US 301/MD 304 interchange project will convert the existing at-grade intersection to a grade-separated interchange with roundabouts.
Workers move a form used for concrete pours on this large box culvert system. Note all of the timber piles in the ground — these serve to keep the drainage system from settling when all of the fill is placed atop it.
