Colorado in need of new ideas to fix old bridges, roads

With Colorado’s recession-plagued budget crisis as a backdrop, there’s been very little meaningful debate this election season about one of the most critical issues facing the state: how to fund desperately needed repairs for Colorado’s crumbling roads and bridges.
This poorly rated bridge on Highway 82 in Glenwood Springs was built in 1953.

According to the Colorado Department of Transportation (CDOT), more than half the state’s 9,000-plus miles of roads are currently rated in “poor” condition, and that number will balloon to more than 75 percent by 2030 if CDOT keeps up its current pace of spending just over $250 million a year on resurfacing. And that doesn’t even address the state’s 128 structurally deficient bridges rated in poor condition.

CDOT officials say they need another $500 million a year just to get to an acceptable level of road and bridge repairs and maintenance statewide, and an unpopular vehicle registration fee hike passed in 2009 – the Funding Advancements for Surface Transportation and Economic Recovery (FASTER) bill – hasn’t even made a dent.

“In this economy, raising taxes to pay for highways would be a nonstarter,” said state Sen. Al White, R-Hayden. “I don’t think the citizens would go for that and that’s why I don’t think you’ve heard any politicians talk about transportation, because they don’t have any solutions. So if you don’t have a solution, better to just not bring it up.”

White, who isn’t up for reelection in November, said FASTER (a Tea Party target viewed by many as backdoor tax by the legislature) was supposed to bring in an additional $250 million a year. But collections have been lagging because of the recession, with fewer people registering new cars and trucks.

“The FASTER dollars that we passed were supposed to be only half of what we minimally needed,” White said. “CDOT said we need a half a billion minimally to maintain a grade C level maintenance on our highways, and that it was closer to a billion to do it in a way that we could be proud of, and I don’t see those dollars coming from anywhere.”

State Rep. Christine Scanlan, D-Dillon, who is running for reelection and whose district is bisected by one of the state’s worst choke points – Interstate 70 – said it will be up to the next governor to make transportation a priority.

“FASTER is a Band-aid under any circumstances; it wasn’t a fix,” Scanlan said. “Whoever is governor is going to have to confront how do you rank transportation versus education, versus health care, versus some of the other general fund tensions. The legislature can only do so much without the governor saying, ‘This is a priority.’”

Scanlan said it will then take a bipartisan effort in the legislature to come up with a package of funding options that will be palatable to Colorado voters. A number of controversial solutions have been floated – from increased tolling to charging motorists by the Vehicle Miles Traveled (VMT) to raising the state gas tax – but none are likely to be popular.

“Or if it’s something different, because I actually don’t think Vehicle Miles Traveled has a chance,” Scanlan said. “The gas tax, those are declining revenues with more fuel-efficient vehicles, so maybe there’s [another] solution we haven’t figured out yet.”

So far the most substantive transportation discussion in the governor’s race — which pits Democratic Denver Mayor John Hickenlooper against GOP nominee and Tea Party favorite Dan Maes and third-party candidate Tom Tancredo – has centered on improving skier traffic between Denver and the mountain resorts along I-70.

Hickenlooper suggested semi-trailer traffic should be curtailed during peak skier periods such as Friday afternoon, Saturday morning (westbound) and Sunday afternoon (eastbound). That idea is unpopular with the trucking lobby but attractive to the ski industry.

Another idea being studied by CDOT is installing “zipper lanes,” or temporary lane dividers, that would increase the number of eastbound lanes to three on Sunday afternoons while restricting westbound traffic to one lane. Estimated to cost between $30 million and $35 million, zipper lanes would cut travel time eastbound between Silver Plume and El Rancho in half, while doubling the travel time westbound.

Predictably, zipper lanes are favored by the ski industry but viewed with some concern by the trucking lobby.

“There’s no silver bullet solution for I-70,” said Melanie Mills, president and CEO of state ski industry lobby Colorado Ski Country USA. “We think the zipper lanes are a promising near-term measure that will improve the eastbound user experience significantly on Sundays. We support implementing the zipper lane assuming important issues such as snow removal and emergency services can be addressed.”

Greg Fulton of the Colorado Motor Carriers Association trucking lobby says his members aren’t totally adverse to the idea but need to know more.

“We’re waiting like everyone else to see some of the results [of more CDOT study] and how it would work,” Fulton said. “On our end, we’re having vehicles in both directions. The only thing we get concerned with is that we don’t adversely affect that other direction, and that’s going to be part of that study.”
This steel truss bridge in Gunnison County is "functionally obsolete." It was built in 1926.

Besides improving the flow of traffic – CDOT has spent about $30 million over the last decade studying the environmental impacts of upgrading I-70 – there is the arguably more immediate issue of road and bridge repairs along the corridor.

A recently released CDOT plan calls for $20 billion in improvements on I-70 over the next 40 years, including $10 billion for high-speed rail, but critics say that plan may obscure the need for short-term fixes and immediate repairs and maintenance. Not to mention there’s no permanent funding source for any of it.

Between Glenwood Springs and the Front Range foothills there are eight structurally deficient bridges along I-70 that are rated in poor condition – four in Clear Creek County, three in Eagle County and one in Garfield County – and none are currently being repaired.

Of the 128 “poor” bridges statewide, only nine are currently under construction using FASTER dollars, although another dozen or so are being repaired using American Recovery and Reinvestment Act (stimulus) funds.

“The reason we didn’t do more is that there was a requirement for stimulus dollars to be spent quickly on shovel ready projects, so there are many resurfacing projects as well,” said CDOT spokeswoman Stacey Stegman. “It’s easier to design a resurfacing project than a bridge project, so we had more of those.

“We are still on the tail end of the stimulus — as those funds are on a reimbursement basis — so we have about another year to go of that work. After that, though, it’s going to be tough.”

I am a licensed Civil Engineer (Transportation) in Oregon. Previously, I was a bridge designer for the state of Iowa. Unfortunately, the best user fee is a gas tax. A 15 cents a gallon federal/state/local gas tax to cover police/fire/ambulance/maintenance/repair/replacement/drainage of roads should be enacted. Insurance companies and phone companies raise rates all the time and we do nothing. It is probably cheaper per month for nearly every American than the cost of cable television and will save on car repairs. As much as 50% of the cost of a structure is staging so that a portion can be built at any one time. This cost is not fixed, but it is an ever increasing portion of construction costs. Bridge costs have previously been managed using a combination of prestressed concrete and cast-in-place components. In order to get more productive per dollar, more prefabricated components need to be used. Bridges further need to be divided into single or double lane structures so that one lane or one of the structures can be serviced without affecting the other half or other lanes of the bridge. A paint that molecularly bonds to steel was developed at the state of Iowa the should be acceptable for steel structures. Additionally, never put asphalt on bridges. Products like ResinPave should be used instead of asphalt binding agents. Drainage should be gutter flow to clean catch basins to bioswales to minimize piping.
Another large portion of costs is labor. Labor is reduced with prefabricated components and fast tracked projects. Safety and supervisor field positions should be held by police officers. Why pay someone to drive a state vehicle all day without the ability to act quickly in case of emergency.
Additionally, state personnel offices and human services should have a significant portion of employees that are police officers/paramedics since education is often identical as are investigative services and emergency needs.
