Summer Paving is Underway

Updated July 23, 2014
NOTE: Paving work was rained out on Tuesday and Wednesday, July 22-23 because asphalt doesn't stick well in the rain. Work scheduled for the 22nd will be postponed until the 24th.

The city's summer paving work started on July 1st.  Summertime weather brings ideal paving conditions.  Paving is done on roads with severe cracks and potholes and on busy streets where the road surface is subjected to the daily pressure of thousands of vehicles. The process involves the application of a couple inches of new pavement to the existing street. This restores the structural strength of the roadway.

Construction on Tigard’s Permit Center Coming Soon

Kim McMillian, P.E.
Project Manager, City of Tigard
503-718-2642 direct
503-866-5784 cell

Tigard’s exterior siding repair project, referred to as “the Wrap,” will be underway in August 2014. The city’s contractor will replace the failing siding on the Permit Center located at 13125 SW Hall Boulevard.  Improvements will also include replacement of the metal gabled roof, which has reached the end of its useful life and the entrance canopy, which currently drains improperly.  Much of the landscaping surrounding the building is overgrown and in poor health. It will be removed, and new landscaping will be installed once construction is complete.

The project is funded with $1.6 million of the city’s general funds set aside for repair and maintenance of public facilities.  The project will be completed in two phases.  The first phase, (August 2014 to November 2014), involves construction on the Permit Center.  The second phase, (July 2015 to November 2015), involves the same type of work on the City Hall and police buildings. 

Work is scheduled to start in early August 2014. The Permit Center will remain open while the project is underway.

New signage, deck seal coming to OR 217 ramp

The advisory speed on the ramp from I-5 to OR 217 northbound is 35 mph

ODOT’s study of the I-5/OR 217 northbound ramp has found no structural issues that would lead to an increase in crashes. Our review of historical data shows speed too fast for conditions has played a role in almost two-thirds of all 82 reported crashes on the ramp in an 11.5-year time period, between the time it opened in June 2001 and the end of 2012. Average traffic volume grew from 24,080 a day in 2002 to 32,160 a day in 2012. That computes to more than 100 million vehicle trips across the ramp since it opened—or almost 1 million vehicle trips each month.

“We are taking even more steps to raise awareness that the advisory speed is 35 mph,” said Jason Tell, ODOT manager for the Portland area. “And wet roads require greater care when driving, especially on any ramp.”

What ODOT has done to study the issue

  • ODOT bridge engineers examined the bridge joint near the beginning of the bridge in January 2014 as part of a routine bridge inspection performed every two years. After reports of new crashes this spring, ODOT inspectors again examined the joint. In both cases, they found the joint within specifications. The current condition of the joint has not noticeably changed since 2006.

  • ODOT bridge engineers examined the structure itself—the piers and foundation, as well as the joints and deck. They found no issues of concern.

  • ODOT crews performed a friction test on the deck of the bridge. The test showed some parts of the deck had greater friction than the last test in 2007 and some parts had less.

What ODOT is doing to reduce further crashes on the ramp

  • ODOT plans to install an electronic warning sign at the start of the ramp by this fall. The sign will display an image of a skidding vehicle when laser sensors detect that rain, snow or ice has reduced road surface traction. Similar signs were installed last winter on the ramp at the north end of OR 217 where it joins U.S. 26 westbound.
ODOT installed a lighted variable message sign at the start of the ramp in May in response to concerns about crashes, to remind travelers of the advisory speed. This sign will be removed when the electronic sign described above is installed.

  • We installed large and bright 35 mph speed signs on both sides of the ramp. And we installed large chevrons (arrows) along the first curve of the ramp.
As part of routine maintenance and in an abundance of caution, ODOT will seal the deck by mid-August.

  • ODOT will record a camera feed documenting traffic patterns on the ramp when the roadway is wet. Speed can be determined from the images. ODOT generally does not record images from our cameras, but we will do so in this case, specifically to study ramp traffic patterns in wet weather.

Street Fair August 16th, 2014

Construction along 72nd Ave continues...

Construction along 72nd Avenue and at the intersection of 72nd Avenue & Dartmouth Street is underway and will continue through November 2014. Those traveling through the area should expect some delays with night-time work and standard roadway construction activity and noise. 

When construction is completed, we'll have a better functioning intersection at 72nd Avenue and Dartmouth Street with improved travel times. Signals will replace the four-way stop.

In late September, 72nd Avenue will be closed from Dartmouth south to Elmhurst Street. A section of 72nd Ave. will be widened to five lanes with sidewalks, bike lanes, and street trees. A sanitary sewer upgrade along 72nd Avenue will be timed to coincide with the road work.  The city expects the closure to last about 3 weeks; the road will re-open in mid-October.

ODOT will announce RealTime technologies

New systems to help motorists navigate through busy traffic will begin Thursday

ODOT on Thursday will announce the first of three new technological innovations that will help travelers navigate through highway congestion.

The ODOT RealTime systems will be unveiled during a news briefing at 10 a.m. Thursday July 10 in the Emergency Operations Center at ODOT’s Region 1 offices, 123 N.W. Flanders St., Portland.

The news briefing will include a presentation on the technologies involved and a video describing the systems. Speakers will include Jason Tell, ODOT’s Region 1 manager, and representatives of Tualatin Valley Fire and Rescue.

The systems will employ sensors in the roads that convey travel times to motorists and establish advisory speed limits telling motorists to slow down for a crash, stall or other delay in the road ahead.

The three systems are
Portland area travel time signs, launched Thursday. The signs will automatically display real time travel times, in minutes, to major interchanges based on road sensors, throughout the Portland area.

OR 217 traveler information signs, launched Summer 2014. New signs will offer travel times, advisory speeds and traveler information on new full-color, 30-foot wide, LED signs.
I-5/405 traveler information signs, launched Summer 2014. The signs on southbound I-5 and I-405 around the Marquam Bridge, will show advisory speeds warning of slowdowns ahead.
Once deployed, the systems are expected to help decrease the number of crashes on Portland roadways, resulting in fewer injuries and fewer costly car repairs.
