We’ve all dealt with the headaches and hassles of the Mercer East construction phases as SDOT works to turn Mercer into a two-way street between I-5 and 1st Ave N. Well, get ready, Mercer West starts in April, just a few weeks away. The Mercer West phase continues through mid-2015.

The April construction begins the widening of Mercer to 3 lanes in each direction between Dexter and 5th Ave N, converting the existing four eastbound lanes to two lanes in each direction between 5th Ave N and 1st Ave N.

First up in this phase is widening Mercer under the SR 99 overpass and reconstructing the SR 99 bridge – during this construction, Mercer will be reduced to two eastbound lanes between 5th Ave N and Dexter starting in May and SR 99 will be reduced to two lanes in each direction between Harrison St and Valley St.

In late April, to prep for construction impacts, signal adjustments and additions are on tap for the intersections of 5th Ave N & Harrison St, Dexter & Republican, and Broad & Harrison. Broad St will also be re-opened to two-way traffic during this phase.

When completed, Mercer will have additional left-turn lanes, widened sidewalks, and a bicycle path between Dexter and 5th Ave N. Roy St will also become a two-way street with bicycle lanes between 5th Ave N and Queen Anne Avenue N.

If you have any questions or concerns about this phase of Mercer construction, there’s a free public Open House tonight (Thursday) with SDOT and the construction company.  It’ll be held at the Seattle Center Rainier Room from 4:30pm to 7pm.

As part of the ongoing Mercer Corridor Project (but really, it’ll be done one day), new Mercer eastbound lane restrictions begin this Monday, December 10th.

According to SDOT, the lane restrictions will last “approximately two weeks” as SDOT installs new signal poles and mast arms at the intersection of Mercer and Fairview Ave N. Two eastbound lanes on Mercer will remain open to traffic between Terry and Fairview. The work will occur on weekdays between 9am and 3pm. A uniformed SPD officer will facilitate traffic flow, but we all know it’ll still be messy.

The Seattle Department of Transportation will begin intermittent nighttime lane closures on Mercer Street today, Monday, August 29, as part of ongoing work on the Mercer Corridor Project.

The I-5 Mercer Street on and off ramp closure scheduled to take place this weekend, from late Friday night, August 26 to early Monday, August 29, has been canceled. From SDOT:

This cancellation is being made in order to accommodate the many nearby events taking place this weekend which are expected to draw large crowds. The cancellation of this weekend’s scheduled closure will likely result in an extra weekend closure possibly in October.

The next planned full weekend closure of the I-5 Mercer Street on and off ramps is scheduled to take place from 11 p.m. on Friday, September 9 to 5 a.m. on Monday, September 12. From SDOT:

Additional full weekend closures in September may be announced—further notification will be provided as dates are finalized.

Detour route maps are available on the project website at: www.seattle.gov/Transportation/ppmp_mercer.htm. Detour routes shown will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound.

During these closures, the I-5 on-ramp at University Street will be concurrently closed to provide more efficient traffic flow around the closed Mercer Street exit lane. Fairview Avenue N will also be closed between Mercer Street and Valley Street and Mercer Street will be closed to through traffic between Westlake Avenue N and Fairview Avenue N. All detour routes will be clearly marked.

Travelers are encouraged to carpool and use alternate modes of transportation. Transit

Once again the Seattle Department of Transportation will be closing down the Mercer Street on and off ramps to I-5 for two full weekends this month in order to do ongoing work required for the Mercer Corridor Project. The closures will take place from 11 p.m. this coming Friday, August 12 until 5 a.m. on Monday, August 15, and again from August 26 to 29 during the same hours.

Detour signs will be posted around the area, but if you’d like to look up the detour routes beforehand, you may download them both here:

In addition to these two closures, WSDOT will be concurrently closing all lanes on SR 520 from 11:00 p.m. Friday, August 26, to 5:00 a.m. Monday, August 29, between Montlake Boulevard and I-405 in Bellevue. (SR 520 from I-5 to Montlake Boulevard will remain open to traffic). Details on this closure and detour maps can be viewed here.

SDOT will also be implementing a number of other nighttime lane closures related to the Mercer Corridor Project throughout the month:

• Beginning as early as Monday, August 1, northbound Westlake Avenue N will be closed overnight between Mercer Street and Valley Street. Northbound traffic, including King County Metro bus routes, will be detoured to Terry Avenue N from 7:00 p.m. to 5:00 a.m. for approximately one week. Southbound traffic will remain on Westlake Avenue N. For King County Metro bus information, please visit Metro Online at www.kingcounty.gov/metro and check the “Alerts Center.”
• Beginning as early as Monday, August 8, nighttime lane closures will occur intermittently on Mercer Street at both Boren Avenue N and Terry Avenue N to accommodate water main installations lasting approximately three weeks. Up to three lanes of Mercer Street will be closed overnight, and Boren Avenue N and Terry Avenue N will have intermittent closures to through traffic between Republican Street and Mercer Street. Work hours are expected to be 7:00 p.m. to 5:00 a.m.

If you venture out of Queen Anne this weekend, keep in mind that traffic is going to be tight both coming and going due to the SDOT’s Mercer Street I-5 on and off ramp closure all weekend long. There are also quite a few special events taking place around town this weekend, including the Capitol Hill Block Party, Chinatown and West Seattle Parades, the Roosevelt Bull Moose Festival, the Swedish SummeRun, various Seafair related events, and quite a few more. Many of these events will mean lane closures, and all will cause higher traffic congestion, so watch out. Download SDOT’s full weekend traffic advisory here (.pdf).

The Seattle Department of Transportation (SDOT) is again closing down the Mercer Street on and off ramps to I-5 this weekend, from 11 p.m. on Friday, July 22, to 5 a.m. on Monday, July 25, to do some construction work related to the Mercer Corridor Project.

SDOT will also be concurrently closing all lanes on Broad Street between Westlake Ave N and 9th Ave N during the same times. Crews will be taking advantage of the anticipated reduced traffic volumes due to the Mercer closure during this time to perform some storm drain work in the intersection of Broad Street and 9th Ave N. From SDOT:

Travelers who planned to use westbound Broad Street over the weekend will be detoured to southbound Westlake Avenue N to Denny Way for access to the Seattle Center and downtown Seattle, or to northbound Westlake Avenue N to 8th Avenue N for access to lower Queen Anne and Dexter Avenue N.

As with previous weekend ramp closures, the I-5 on-ramp at University Street will be concurrently closed to provide more efficient traffic flow around the closed Mercer Street exit lane on I-5. Fairview Avenue N will also be closed between Mercer Street and Valley Street, and Mercer Street will be closed to through traffic between Westlake Avenue N and Fairview Avenue N.

Updated detour route maps are available on the project website at: www.seattle.gov/Transportation/ppmp_mercer.htm. Detour routes will be signed on roadways and may be heavily used, particularly Denny Way in both directions. Travelers are advised to consider alternate routes, SR 99 or alternate I-5 exits and entrances, and to carpool or use alternate modes of transportation.

The Seattle Department of Transportation (SDOT) will be closing down the I-5 on and off ramps at Mercer Street again this weekend, as part of ongoing work needed as part of the Mercer Corridor Project.

The closure will begin at 11 p.m. on Friday, June 17, and go until 5 a.m. on Monday, June 20. Detour route maps are available here. From SDOT:

Detour routes shown will be signed on roadways and may be heavily used, particularly Denny Way both eastbound and westbound. Travelers are advised to consider alternate routes to their destinations such as SR 99 or alternate I-5 exits and entrances.

After this weekend’s closure, the Mercer Street access to and from I-5 will not be closed again until the weekend of July 8-11, and is scheduled to take place during the same hours. From SDOT:

During these closures, the I-5 on-ramp at University Street will be concurrently closed to provide more efficient traffic flow around the closed Mercer Street exit lane. Fairview Avenue N will also be closed between Mercer Street and Valley Street and Mercer Street will be closed to through traffic between Westlake Avenue N and Fairview Avenue N. All detour routes will be clearly marked to support traffic flow around the closures.

SDOT is advising travelers heading to the Fremont Solstice Parade and Fair to use SR 99 or to the alternate I-5 off-ramps at Olive Way (northbound) or Stewart St. (southbound) and Denny Way to Westlake Ave. N. More information on routes to the Fremont Fair can be found at the fair website.

Travelers are encouraged to carpool and use alternate modes of transportation. Transit information can be found at:

Starting next week the Seattle Department of Transportation (SDOT) will begin lengthening the left-turn lanes on Elliott Ave W at W Mercer Place, as part of Phase II of the Mercer Corridor Project.

In preparation for the project, SDOT will be working on adjusting the rim of a utility access hole along Elliot Ave W this week. All construction will take place on weekdays only, during non-peak travel times. Crews will complete the work over the next three to six weeks. From SDOT:

Starting next week, SDOT crews will first remove the current asphalt island, traffic post, overhead sign and concrete curb. Next, they will pave and restripe the roadway which requires fair weather. Finally, they will adjust the traffic signal timing and install a new overhead sign.

The left-turn from Elliott Ave W onto W Mercer Place will remain open during construction, and signage will guide through traffic, according to SDOT. Drivers should expect congestion and added traffic due to the work and lane restrictions. The work will not interfere with access to nearby businesses, and all closed lanes will be re-opened to traffic during the morning and evening peak commuting periods. For more information, visit the project website.

The Seattle Department of Transportation (SDOT) will be closing down the I-5 on and off ramps at Mercer Street this weekend, the final construction closure at this site scheduled for May, an area in the midst of ongoing construction work needed as part of the Mercer Corridor Project.

The closure will begin at 11 p.m. tonight, Friday, May 20, and continue through 5 a.m. on Monday, May 23. After this weekend the Mercer Street on and off ramps will not be closed again until the weekend of Friday, June 17 to Monday, June 20 (also from 11 p.m. until 5 a.m. on those days respectively). From SDOT:

During these upcoming closures, please note that Mercer Street will be fully closed to through traffic between Westlake Avenue N and Fairview Avenue N, including access from Mercer Street to southbound Fairview Avenue N that had been maintained during previous closures. The I-5 on-ramp at University Street will be concurrently closed to provide more efficient traffic flow around the closed Mercer Street exit lane. Fairview Avenue N will also be closed between Mercer Street and Valley Street.

Updated detour route maps are available SDOT’s project website. Signs indicating detour routes will also be visible around the closure. SDOT advises commuters to be prepared for heavy congestion along these detour routes, particularly on east- and westbound Denny Way, and to use alternate routes when available.

The Seattle Department of Transportation (SDOT) is preparing for more weekend-long closures at the Mercer Street on and off-ramp to I-5 throughout May.

Work that is part of Mercer Corridor Project will shut down the on and off-ramps for at least two weekends this month: Friday, May 6 to Monday, May 9, and Friday, May 20 to Monday, May 23. The Mercer Street exit and on-ramp may also be closed for a third weekend, from Friday, May 13 to Monday, May 16, pending final coordination with other major work projects in the area.

The I-5 on-ramp at University Street will be concurrently closed to provide more efficient traffic flow around the closed Mercer Street exit lane. Fairview Avenue N will also be closed between Mercer Street and Valley Street. All detour routes will be clearly marked to support traffic flow around the closures.

Mercer Street ramp closures are required for utility installations on Fairview Avenue N at Mercer Street, including water, sewer, electrical and communications line installations, as well as to align the existing on- and off-ramps with the future westbound lanes of Mercer Street.

During weekend closures, Metro Transit plans to reroute its bus service on routes 70, 71, 72, 73 and 83 off of Fairview Avenue N from 11:00 p.m. on Friday to 5:00 a.m. on Monday. Buses will be rerouted via Eastlake Avenue E: northbound between Mercer Street and Galer Street; and southbound from Galer Street to Thomas Street. Rerouted buses will serve posted stops on Eastlake Avenue E, but will not make any stops on the cross streets between Eastlake and Fairview.

Queen Anne-ers used to taking the Mercer Street on ramp and exit will have to find another way to and from I-5 this weekend. The Seattle Department of Transportation (SDOT) will be closing down the I-5 on and off ramps at Mercer Street in the first of four upcoming weekend closures due to utility improvements and ramp re-alignment work needed as part of the Mercer Corridor Project.

The closure will begin at 1 a.m. on Saturday, April 16, and run until 1 a.m. on Monday, April 18. There will also be a concurrent closure of the northbound I-5 on-ramp at University Street to improve safety and provide more efficient traffic flow around the closed Mercer Street exit lane.

Detour routes will be clearly market during the closure, though you can download the official detour maps here for access to I-5 and from I-5. From SDOT:

Three additional full weekend closures are tentatively scheduled and closure hours are anticipated to be Friday at 11:00 p.m. to Monday at 5:00 a.m.; further notification will be provided as the dates are finalized:

• May 6 – May 9
