SALEM -- Lawmakers on Monday unveiled a proposed package of vehicle fee, payroll and gas tax increases that would raise $8.2 billion over the next decade to ease congestion and improve state and local roads, bridges and public transportation.

The plan includes money for added lanes on Interstate 5 and Highway 217, as well as widening of Interstate 205.

The ambitious plan is a top priority for the Legislature and Gov. Kate Brown this year, after they failed to pass a smaller transportation package in 2015.

Lawmakers have for months been debating in public and private meetings how to raise money for the work. They put together a $5 billion wish list of projects earlier this year, and have been working on how to pay for it.

The framework released Monday largely reflects the revenue options discussed so far this year, such as the gas tax and vehicle registration fee increases and statewide payroll tax. Half of the new vehicle fee and gas tax revenue would pay for state transportation projects, 30 percent to counties and 20 percent to cities.

The transportation package work was led by the two Democrats and two Republicans who head the Joint Committee On Transportation Preservation and Modernization: Sen. Lee Beyer, D-Eugene, Rep. Caddy McKeown, D-Coos Bay, Sen. Brian Boquist, R-Dallas and Rep. Cliff Bentz, R-Ontario.

Although House Speaker Tina Kotek, D-Portland, said earlier this year she'd prefer a package without specific projects, the proposal released Monday takes aim at some of the state's most serious bottlenecks.

The plan calls for state money, along with matching funds from local jurisdictions, to fund several projects throughout the state to reduce traffic congestion, including the following:

>> $450 million to add lanes and fix a ramp on I-5 in the Rose Quarter

>> $202 million to widen and retrofit Abernethy Bridge on I-205 to withstand earthquakes

>> $250 million to widen I-205 between Stafford Road and Oregon City

>> $98 million to add lanes in both directions on Highway 217

>> $30.7 million for traffic management and bottleneck projects on I-205

Tolling has also been considered to decrease traffic in the Portland area. Boquist said a Portland-area tolling plan would likely include tolls on both I-5 and I-205, though some stretches might be toll-free to decrease the burden on low-income Oregonians.

Beyer said a recurring complaint from businesses throughout Oregon was that the Portland-area traffic was costing them money.

"We forget sometimes that we're an exporting state, and all the freight – the economy of Oregon – has to go that way," he said. "We're hurting our job expansion, we're hurting the economy. ... It's just a question of do we want to address it or not?"

Boquist noted that the state has underfunded transportation for decades. As Oregon's population has grown, this has led to increased congestion, and not just in the Portland area, he said. In addition, Oregon's infrastructure is in need of seismic improvements as a threat of a mega-earthquake looms.

The state's gas tax revenue has slackened in recent years as more Oregonians turn to fuel-efficient vehicles. Monday's plan seeks to address this adding a tiered fee system that requires owners of efficient vehicles to pay more. It would also create a new tax on bicycle sales to pay for standalone bike paths.

The proposal calls for the following tax hikes over the next decade:

>> Increasing the gas tax by 14 cents, to 44 cents per gallon

>> Increasing title fees by $40, to $117

>> Increasing registration fees by $40, to $83, and adding a tiered structure

>> 0.1 percent payroll tax

>> 5 percent tax on new bicycle sales

>> 1 percent tax on new vehicle sales

McKeown said relying on several different funding streams spreads the burden more evenly among Oregonians.

"We're asking everybody to do their part here," she said.

Monday's meeting was primarily informational. While presenting the plan, Boquist said the committee will meet again on Wednesday, when members will debate components of the plan.
