Maryland Gov. Larry Hogan (R) on Thursday proposed a $9 billion plan to widen three of the state’s most congested highways — the Capital Beltway, Interstate 270 and the Baltimore-Washington Parkway — in what he said would include the largest public-private partnership for highways in North America. The projects would add four toll lanes each to Maryland’s portion of the Capital Beltway (I-495) and to I-270 from the Beltway to Frederick. It would also widen the Baltimore-Washington Parkway (MD 295) by four toll lanes after taking over ownership from the federal government. Because of private-sector involvement, Hogan said, the plan would...

Motorists on Interstate 270 could start seeing lane closures next week as construction crews begin resurfacing and restriping a highway spur that leads to the Beltway. The work marks the beginning of a $100 million project to ease traffic backups on the roadway, according to state transportation officials. “This is the first step in a major project to break daily gridlock,” Maryland Transportation Secretary Pete K. Rahn said in a prepared statement. The initial phase of the effort involves surfacing improvements on the section of I-270 that connects with the outer loop of the Beltway. The project, which is expected...

Dive Brief: The Pennsylvania Department of Transportation (PennDOT) has announced the completion of the state's first-ever diverging diamond interchange (DDI), located on Interstate 70, according to Equipment World. The DDI design eliminates left turns across oncoming traffic, improving vehicle flow and decreasing the chance of accidents. The agency also chose the DDI configuration because it could use the former interchange's cloverleaf footprint, reducing the impact of construction on the area. PennDOT said it modified the traditional DDI design slightly. Dive Insight: Design is one way transportation agencies are combating gridlock resulting from increased traffic. Other tools in DOT arsenals are...

The northbound lanes of a main section of the West Sam Houston Tollway/Beltway 8, which were flooded by Tropical Storm Harvey, were reopened Sept. 7 after pumping out standing water, but the southbound lanes likely won’t open until the middle of this week, according to the Harris County Toll Road Authority in Houston. The authority reported Sept. 7 that the tollway section from Westheimer to Interstate 10 was a lake, with 14 feet of water, when pumps arrived. By then, the water had finally receded enough for the authority and the Texas Department of Transportation to start pumping out the...

SURFACING MODELS OF THOUGHT Out of the complexity of the global sand trade has emerged something of a butterfly effect, in which an economic decision in one place can wreak social and environmental havoc on the other side of the world. If you’re looking for a way to express something that’s staggeringly hard to count, you won’t find a more reliable metaphor than grains of sand. There is indeed quite a bit of it – about 7.5 quintillion grains on Earth’s beaches and deserts, according to one estimate. But if you think that this would be sufficient to supply an...

HARRISBURG, PA. (July 18, 2017) — At its bimonthly meeting today, the Pennsylvania Turnpike Commission (PTC) approved a six percent toll increase for both E-ZPass and cash customers; the increase is set to take effect at 12:01 a.m. on Jan. 7, 2018. Because of today’s action, the most common toll for a passenger vehicle will increase next year from $1.23 to $1.30 for E-ZPass customers and from $1.95 to $2.10 for cash customers. The most common toll for a Class-5 vehicle — a prevalent tractor-trailer class — will increase from $10.17 to 10.78 for E-ZPass and from $14.45 to $15.35...

Suburban housing construction has ground to a halt in Northern Virginia, according to county officials from the region, due to a law that changed the state's proffer system. "New home development has slowed across Northern Virginia since new rules kicked in last summer limiting what public infrastructure developers were allowed to pay for as part of new construction projects," reports Max Smith. That assessment was delivered by elected officials from around the region attending a meeting on the subject earlier this week. Officials from Loudon, Fairfax, and Prince Williams counties agree that housing construction has slowed since the law took...

“We have bridges that are falling down,” then-candidate Donald Trump told Fox last August, pledging to double the amount Hillary Clinton wanted to spend on infrastructure as president of the United States. “We’ll get a fund, we’ll make a phenomenal deal with the low interest rates and rebuild our infrastructure.” One year later and eight months into his presidency, Trump has continued to double down on his lofty promises — during “Infrastructure Week” in June, he told his supporters in Cincinnati that the U.S. “deserves the best infrastructure in the world.” But the administration has been slow to move its...

LAKE MEAD (FOX5) - A section of Interstate 11 opened Wednesday between the 95 and Railroad Pass Casino. But some drivers said they are having a hard time navigating it, thanks to a glitch from GPS technology. When a 2.5 mile stretch of I-11 opened, Apple and Google maps didn't register it. Instead, it caused a major glitch, and instead of routing people down the 95 toward Boulder City and Arizona, drivers were being redirected all the way through Lake Mead National Park. The route takes more time and also comes with a $20 toll. "I pulled over with all...

Local entities involved in the proposed Interstate 15 Siphon Road interchange signed off this week on plans to start construction on a project expected to dramatically increase the Pocatello area’s population and greatly improve the local economy. Those behind the effort to build the interchange say that with its construction, the area north of Pocatello and Chubbuck will see massive development in the future, including a technology park employing thousands of people, shopping centers, dozens of new neighborhoods, parks, trails and even new concert venues. But before such unheralded growth can occur, the interchange needs to be built. While the...

Everyone in America was planning for the solar eclipse on August 21, except, apparently, the Montana Department of Transportation. That day, a contractor hired by MDT had scheduled a fairly major road construction project to begin on Interstate 15 near the Clark Canyon Dam. As tens of thousands of people headed north from the path of the eclipse to get home Monday around 4:30 p.m., they encountered a miles-long traffic jam that slowed traffic to a bumper-to-bumper crawl for more than an hour for some drivers. The flow of traffic was not a problem on the northbound lane of I-15...

MADISON -- The state Department of Transportation has scrapped new bids on the massive Zoo Interchange project as lawmakers put the long-delayed state budget on the back burner and focus on Foxconn incentives instead.A special session will start at 11 a.m. Tuesday, August 1st on a bill that would extend $3 billion in tax breaks to the Taiwanese electronics company Foxconn, which has pledged to build a multi-billion dollar plant in southeastern Wisconsin and hire thousands of workers. A public hearing could happen this week.Meanwhile, Wisconsin's budget is a month late. Without funding, the state DOT has withdrawn three proposals...

Christiana Briganti-Dunn is a civil engineer who oversees design-build projects for the Virginia Department of Transportation, but two years ago, she found herself holding a set of paint swatches up against a wall like a homeowner planning a kitchen renovation. The wall was at Chapman Mill, a five-story stone gristmill built in the 18th century near Broad Run, Va. Christiana’s job was to pick colors that would be painted on a set of bridge abutments on nearby Interstate 66. Everyone wanted the bridges to look pretty. “When we were meeting with the communities of Haymarket and western Prince William County,...

To officially take control of the project, the Indiana State Budget Committee had to approve the plans. Additionally, all parties had to endorse a settlement agreement and bondholders had to be paid in full.The finance authority announced Monday it had completed the settlement transaction to terminate the contract with I-69 Development Partners...

MOLINE -- Building the new Interstate 74 bridge will take years, but certification to bid on the jobs building it should only take about 90 days. The Illinois Department of Transportation held a Disadvantaged Business Enterprise certification and supportive services workshop Monday evening at the Moline Public Library, 3210 41st St. At the workshop, officials from IDOT shared information on how those who are in presumed disadvantaged groups can bid on contracts associated with the project. To qualify for DBE certification, the business owner must have a personal net worth of less than $1.32 million. Engineering consulting businesses must average...

The widening of Interstate 66 outside the Capital Beltway is bringing HOT lanes to one of the region’s most congested corridors. It also will make room for bicyclists and pedestrians — putting them on a trail next to one of the region’s busiest and most congested highways. The bike path, part of the $2.3 billion interstate expansion project, has drawn cheers and criticism from biking aficionados who welcome the addition of the trail but say, if built as proposed, users will be too close to cars whizzing by on the interstate and exposed to toxic exhaust fumes. For about five...

LONDON — The rest of the planet bears a warning for President Trump’s plan to lean heavily on private business in conjuring a trillion dollars’ worth of American infrastructure: Handing profit-making companies responsibility for public works can produce trouble. In India, politically connected firms have captured contracts on the strength of relationships with officialdom, yielding defective engineering at bloated prices. When Britain handed control to private companies to upgrade London’s subway system more than a decade ago, the result was substandard, budget-busting work, prompting the government to step back in. Canada has suffered a string of excessive costs on public...
