WK 07-15: WASHINGTON –LAKE WASHINGTON SHIP CANAL - LAKE WASHINGTON – SR-520 Special Bridge Notice - Critical Navigation Notice (Revised from LNM 52/14) Part A
The center drawspan has been permanently blocked as of 17 Feb 15. Marine traffic will no longer be able to use the draw span to navigate through the SR 520 floating bridge and the new floating bridge will not have a draw span. The East Channel is now open and provides 58 feet of vertical clearance. The West Channel is open and provides 45 feet of vertical clearance. When the old bridge is removed in approximately Oct 2016 the East channel will provide its permanent vertical clearance of 70 feet.

East Span:
  • 1. Navigation vertical clearance at the east span is restricted to 58 feet until approximately Oct 2016 when the full 70 foot vertical clearance will be established. The eastern navigation channel will be marked with red and green navigational buoys as shown in Enclosure (7). The eastern navigation channel varies from 168 feet to 200 feet in width with the majority of it being over 180 feet wide.

There are three known instances in which the eastern navigation channel will be completely obstructed for construction activities, they are listed below:
  • 1. Approximately 2 Days per Week - Concrete Pours - KGM will obstruct the channel between roughly 0400 and 1000 Hrs to allow concrete trucks to drive onto the pontoons during pours.
  • 2. Late Feb/Early Mar 15 - Dry Finish on East Approach Bridge - Barges may be maneuvering in the area at night.
  • 3. Late Apr 15 - North Transition Span Set - Barges will be maneuvering in the eastern navigation channel intermittently over a 3 day period approximately 12 hours each day.

During these instances, marine traffic with vertical clearance requirement of less than 45' can continue to transit through the west navigation channel. For vessel with vertical clearance requirements between 45' and 58' needing to transit under the east channel during these times should make arrangements with the Contractor, Monica Blanchard, at (206) 913-7498 or mblanchard@mansonconstruction.com or David Bowman, at (360) 300-7055 or david.bowman@kiewit.com

  • 2. Eight temporary pilings (two groups of four pilings) marked with yellow lights flashing every 4 seconds (Fl Y 4s) have been placed in the southeast part of Union Bay near the west end of the bridge for the temporary mooring of pontoons. Refer to LNM 05/13 chart 18447 for temporary chart corrections.
  • 3. The west channel has a vertical clearance of 45 feet.
  • 4. 12 temporary barge mooring pilings have been placed on the north side of the bridge just west of the west navigation channel. All 12 pilings are marked with quick flashing yellow lights (QY), which may be obscured at times when barges and other equipment are moored at the site.

West Approach Project:
A temporary trestle structure is being constructed along the existing SR-520 bridge. It will extend from the west end off the existing SR520 bridge and extend to the new SR520 bridge construction. The trestle will be lighted with white flashing lights spaced every 100 feet and with retro reflective material. Construction of the trestle will be Monday through Saturday, 0700 until 0500 the next day. The temporary trestle will be in place until Jun 17. No public access will be allowed near or under the structure, and mariners are requested to approach the construction no closer than 300 feet.


WK 06-15: OREGON - WASHINGTON - IDAHO - Bridge information is being added to Light List Volume VI
In an effort for mariners to more easily identify bridges throughout the 13th Coast Guard District, information is being added to Light List Volume VI for bridges in Oregon, Washington and Idaho that are located in waterways covered by the Light List. The position information being listed for each bridge is not meant to be used for navigation and is only to help the mariner with identifying a particular bridge in a waterway. Mariners​ are advised to refer to the chart for detailed navigation information for a bridge. Mariners are asked in the future when reporting a problem with a bridge to the Coast Guard to include the Light List number for the bridge they are reporting. For more information regarding the 13th Coast Guard District Bridge program go to http://www.uscg.mil/d13/dpw/bridges.asp.


WK 06-15: LAKE WASHINGTON SHIP CANAL – LAKE WASHINGTON – SR-520 SPECIAL BRIDGE NOTICE – Center drawspan
and east navigation channel blockage and passage opportunity for vessels over 45 feet in height
Prior to blocking the center drawpsan of the existing SR-520 bridge on the morning of Tuesday 17 Feb 15, Kiewit-General-Manson will be opening the eastern navigation channel for the passage of vessels. The eastern navigation channel will be marked with red and green navigational buoys as shown in Enclosure (8). The eastern navigation channel varies from 170 feet to 200 feet in width with the majority of it being over 180 feet wide. There are three known instances in which KGM will need to block the eastern navigation channel for construction activities, they are listed below:
  • 1. Approximately 2 Days per week during February and March – Concrete Pours – KGM will block the channel between roughly 0400 and 1000 Hrs to allow concrete trucks to drive onto the pontoons during pours.
  • 2. Late February/Early March – Dry Finish on East Approach Bridge – Barges will be maneuvering in the Nav channel intermittently over a 3 day period.
  • 3. Early April 2015 - North Transition Span Set – Barges will be maneuvering in the eastern navigation channel intermittently over a 3 day period. During these instances, marine traffic shorter than 45’ tall can continue to transit through the west navigation channel.

WK 04-15: LAKE WASHINGTON SHIP CANAL – Fremont Bridge Special Bridge Notice (Revised from LNM 03/15)
The U.S. Coast Guard has issued a temporary deviation from the normal operating schedule that governs the Fremont Bridge, across Lake Washington Ship Canal at mile 2.6 from 0700 on 28 Jan 15 until 1800 on 01 May 15. This deviation allows the bridge to operate in single leaf mode while work crews are onsite, and provide a double leaf opening only with a five hour advanced notice is given to the bridge operator. This deviation also allows one half of the bridge to remain in the closed position while reducing the vertical clearance of the non-operating span up to four feet. A temporary deviation is needed for structural painting of this historic landmark. The Fremont Bridge provides a vertical clearance of 14 feet (31 feet of vertical clearance for the center 36 horizontal feet) in the closed position. The clearance is referenced to the mean water elevation of Lake Washington. Work platform(s) will be used on both the north and south spans respectively as work proceeds. The signs will be flagged to draw mariner’s attention to the change in vertical clearance. The bridge will be able to open one leaf, half of the draw span, for vessels engaged in emergency response operations during this closure period. The bridge shall operate in accordance to 33 CFR § 117.1051 at all other times. In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the designated time period. For further information, contact the Seattle Department of Transportation at (206) 386-4234/Operator’s tower, (206) 386-4251/Evening Operator, or (206) 305-3486/ Foreman.


WK 52-14: LAKE WASHINGTON – SR-520 Special Bridge Notice - Critical Navigation Notice Part A (Revised from LNM 51/14)
As early as February 2015, construction activities for the new floating bridge will completely block the drawspan on the existing SR 520 floating bridge. At this time, boat traffic will no longer be able to use the draw span to navigate through the SR 520 floating bridge. Vessels more than 58 feet tall will not be able to navigate beyond SR 520 until the existing bridge is removed from Lake Washington, currently planned for late 2016. The new floating bridge will not have a draw span, but the east navigation channel will be 70 feet tall when complete. 

Until the center draw span is permanently blocked in February of 2015, the U.S. Coast Guard has revised the draw span operating schedule for the SR-520 Evergreen Point Floating Bridge. Construction activities will continue for the duration of the bridge replacement project until approximately 30 Aug 15. Vessels which are impacted by the closure of the east channel that are not able to navigate through the west channel of the existing bridge may request an opening of the center draw span for passage. Boaters may request a draw span opening by calling WSDOT at (206) 440-4490. Eight temporary white mooring buoys (six on the north side and two on the south side) marked with white lights flashing every 4 seconds (Fl W 4s) have been deployed near the bridge for the mooring of construction barges and shown as chart corrections in LNM 05/13 for chart 18447. For up to date schedule changes and special event schedules for the SR-520 Bridge, please visit WSDOT’s web site at: http://www.wsdot.wa.gov/Projects/SR520Bridge/BridgeAndLandings/DrawspanInfo.htm.
