Agency-wide Stormwater Management Improvements

MDOT MPA, WBCM, P. Flanigan & Sons

The project identified existing areas across MPA facilities that could be retrofitted to feature stormwater management (SWM) best management practices (BMPs). Five existing drainage swales that receive runoff from large impervious areas but that did not provide SWM treatment were identified and converted to MDE-approved BMPs. The resulting facilities treat over nine acres of additional impervious area. New BMP facilities consisted of one new surface sand filter, one new wet swale, one new bioretention facility, and two new submerged gravel wetlands.

Bradshaw Road Bridge over I-95

MDOT MDTA, GPI, Stantec, Six-M

MDTA replaced Bradshaw Road over I-95 as the kick-off project for the Northbound Extension of the I-95 Express Toll Lanes. The bridge was lengthened, and the profile raised slightly to accommodate the future full width of I-95. The architectural treatment developed for this project served as a basis for follow on structures on the Northbound Extension of the I-95 Express Toll Lanes. The semi-integral abutments and corrosion resistant reinforcing were a first for MDTA and will reduce maintenance costs over the life of the bridge. With Six-M’s experience on several bridge projects for MDTA along the I-95 corridor, they completed the project within schedule and obtained the full incentive by opening the bridge 30 calendar days early.

Ellicott City 2018 Flood - Ellicott Mills Drive Culvert and Road Repairs

Howard County, Wallace Montgomery, Allan Myers

The Ellicott City 2018 Flood was heart-wrenching following closely behind the 2016 Flood. The failed culvert, as designed, conveyed less than the 20-year Storm Event. The Corrugated Aluminum Plate Culvert corroded and failed via the bottom of the culvert folding upward under the weight of water and debris carried by the 2018 Flood.

The project reduced environmental impacts improved flood resilience and provided the means to economically increase flood conveyance in the future while continuing to protect downstream neighbors today.

The construction included a new precast concrete box culvert with concrete open channels upstream & downstream, stone veneers required by the Ellicott Historic Preservation Commission, reconstructing Ellicott Mills Drive, walking paths, and multiple utility relocations and hardenings.

I-270 at Watkins Mill Road Interchange

MDOT SHA, KCI, Gannett Fleming, GPI, JMT, WSP, WRA, Wagman

The I-270 at Watkins Mill Road Interchange project was a $92 million project to relieve congestion on one of Montgomery County’s most congested corridors. The project scope included a new interchange on I-270 consisting of 14 structures, including a five-span bridge over I-270 and a two-span bridge along an off-ramp. This project was a result of Montgomery County’s desire to create a crossing of I-270 and connect the communities of eastern and western Gaithersburg that were previously separated by the highway. The project provided a critical link to I-270, spurring economic growth for the area, decreasing traffic congestion, and improving the quality of life of residents. Wagman and SHA collaborated on a Value Engineering proposal that reduced costs, risk, and impacts to the traveling public. The project finished 30 days ahead of Wagman’s proposed schedule, and 6 months ahead of the owner’s original completion date.

The project design started in April 2019 and construction completed in November 2019.

MD 213 Bridge over Old Mill Stream Branch

MDOT SHA, RK&K, McLean Contracting

The project constructed a new bridge to replace the existing culvert carrying MD 213 over Old Mill Stream Branch in Centreville, MD. The existing culvert was a two-cell box culvert built in 1912 that was widened in 1945 on both sides with a concrete slab on timber piles. The timber piles and top slab were experiencing significant deterioration. Due to existing traffic volume, the geometry of the roadway respective to the existing culvert alignment below, and concerns that phased demolition would result in an unstable structure, the replacement superstructure was constructed adjacent to the existing structure and moved in place during an extended weekend closure using the innovative Accelerated Bridge Construction technique of lateral sliding. This was the first lateral slide performed by the Maryland Department of Transportation.

The project included the removal and replacement of thirteen (13) rail-highway grade crossings on the MTA owned freight rail lines on the Eastern Shore of Maryland. The existing grade crossings were reconstructed with precast concrete modular panels.

Suitland Road & Regency Parkway Outfall Repair

Prince George’s County, RK&K, Highway and Safety Services

The Suitland Rd & Regency Pkwy Outfall Repair project successfully combined ecosystem restoration w/grey infrastructure to replace a degraded storm drain outfall. The site is downstream of a previous sand & gravel surface mining operation and residential developments. This increase in pavement, rooftops, and other impervious surfaces contributed to increased stormwater runoff & erosive flows. The outfall structure, conveying three storm drain systems, fell forward into the receiving stream channel and threatened the intersection of Suitland Road and Regency Parkway. The outfall channel went from an overgrown drainage ditch to a naturally landscaped stream bed & floodplain that will provide stable conveyance of stormwater runoff, reduce pollutant loadings & provide habitat for wildlife.

US 1 Over Big Gunpowder Falls

MDOT SHA, JMT, Marine Technologies

US 1 (Belair Road) in northeast Baltimore County is a major arterial that carries four lanes of vehicular traffic near Gunpowder Falls State Park. In 1990, a structure was completed consisting of a five-cell corrugated structural plate pipe arch. A separate, 15’ diameter structural plate pipe located on the north bank of the river served as a pedestrian/equestrian passage beneath US 1. All six cells were experiencing advanced deterioration.

The primary issue was determined to be that the galvanizing was not properly oxidized under proper conditions prior to being put into service in a wet environment. The most cost-effective rehabilitation method was an independent structure capable of supporting all loads itself. Five cells were retrofitted with 9-inch-thick, cast-in-place reinforced concrete liner poured inside and against the existing structural plate pipes.

US 15 Access Improvements

MDOT SHA, Century Engineering, C. William Hetzer

This project consisted of the design and construction of safety and geometric improvements at median crossings by implementing J-Turn and R-Cut intersection designs. The purpose of the project was to address safety issues related to crossing and U-turn movements at existing median crossings along US 15. The project included resurfacing and safety improvements and bicycle accommodations. normal section of roadway, the grade at the southern project limit, and for the outside shoulder width at locations with no widening. Another safety improvement was the development of a T-turnaround for Old Frederick Road, thereby eliminating an access point along US 15.
