Musings from an NPS visit

Tonight's MVCCA Transportation Committee meeting featured visitors from the National Park Service and US Park Police regarding the George Washington Parkway. What followed was a quick Q-and-A, mostly related to the section south of Old Town Alexandria which our committee represents. Here's a quick recap of the comments:

• Numerous complaints about increased traffic in BOTH directions of the Parkway during rush hour with BRAC and the new hospital at Ft Belvoir cited as the cause. Excessive speeding by traffic was also mentioned.
  
• Because of the traffic, it's very difficult for drivers to turn out onto the Parkway during rush hour, especially for those turning left. Nevermind the issues that cyclists and pedestrians face trying to cross the Parkway.
  
• On that note, NPS has no current plans to improve bike/ped access to the MVT, though they had considered intersection improvements at Belle Haven Rd at one point. This is problematic since, between the south end of Old Town and the "Stone Bridge" at Alexandria Ave (a little over 3 miles), there is no way for bikes and peds to access the Mount Vernon Trail that doesn't involve hopping a curb and going through grass.
  
• The current (acting) NPS Superintendent has no intention of lifting the GW Parkway bicycle ban. The NPS reiterated that the current policy ban was put into place "in the name of safety".
  
• When asked about MVT improvements, the rep said that NPS is looking into an "express bike lane" in the Gravelly Point area. This would allow through cyclists to avoid the heavy congregation of pedestrians just east of the parking lot that go there to watch airplanes take off and land at National Airport.
  
• US Park Police apparently have data on accidents/crashes that occur on the Mount Vernon Trail proper. They're looking into making that data available to members of the transportation committee.
  
• NPS has automated traffic counters at several locations along the parkway and posts aggregate monthly stats on them. The committee asked if they also have hourly counts, which they'll look into. The hourly counts would give a better idea on when the low-traffic times are on the Parkway.
  

Also mentioned, but not discussed, is a draft resolution offered by WABA and FABB in support of allowing bicycles on the George Washington Parkway. Even though the current NPS Sup has no interest in revising the current ban policy, the committee is willing to entertain the possibility of supporting a partial lifting of the ban during low-traffic times. We'll be discussing the resolution at next month's meeting.

Quick GW Parkway cycling note

Coming out of tonight's Mt. Vernon Transportation Committee meeting: the committee is open to the concept of allowing bicycles on the George Washington Parkway on the weekends. I don't think we have support for an all-weekend allowance, but most of the committee members there tonight are open to the idea of at least partial hours for bikes on the weekend...most likely on weekend mornings.

The next step would be to draft a resolution or letter of support for the Mt. Vernon Council of Citizens Associations to approve and pass on to local elected officials and the National Park Service. As the committee's unofficial bicycle advocate, I've also been asked by the committee chair to invite WABA and FABB to speak at our next monthly meeting.

It's a step in the right direction.

A permanent fix for a problematic spot

A persistent problem spot on the area's bicycle/pedestrian network has been on the George Washington Parkway near Memorial Bridge. In this area, bicycles and pedestrians transiting between the Mount Vernon Parkway and the Memorial Bridge must cross both the northbound GW Parkway main lanes plus a northbound ramp at-grade. The site has been the scene of numerous crashes this year (the latest being a pedestrian right before Halloween), all of which involve either a vehicle hitting a cyclist or pedestrian, or rear-end crashes among vehicles as some drivers stop/slow to allow bikes/peds across and the vehicles following behind do not stop and thus crash.

Even without the crashes, regular vehicle traffic has other concerns. The area is confusing jumble of ramps going all sorts of different directions. All too often, drivers not familiar with the area realize too late that they are in the wrong lane for the particular ramp they want to take and try to change it at the last possible moment. The result is further congestion and the occasional vehicle crash.

Unfortunately, there is no easy fix to the problem. Longstanding National Park Service policy is for no traffic signals along their parkways, so this precludes putting a traffic signal or even a HAWK signal at the location. Ideas for a bike/pedestrian overpass have brought concerns about loss of trees and "overhead obstructions". This has led to more recent calls for a bike/pedestrian underpass, but this will require a fair bit of money and regrading to implement.

Ultimately, something will have to be done. It will be a bitter pill to swallow, but the only way NPS can reduce the crash risk is to do something that either costs a lot of money or goes against their current policies.

To that end, I have devised my own permanent fix that solves many of the problems endemic in the area:



My proposal involves a lot of construction, which NPS may not be very keen on doing and will in turn cost a lot of money. However, it solves many of the safety/traffic problems in the area. Among the benefits:

• Straightens out the GW Parkway main lanes and moves all entrances/exits to the right. The existing configuration has three left-side entrances/exits.
  
• Retains all existing access and greatly streamlines and simplifies the ramps connecting the GW Parkway to Memorial Bridge, Route 27, and Route 50 West.
  
• Elimination of many of the existing roads/ramps allows for renaturalization/revegetation of those ramp locations to mitigate the loss of trees due to construction.
  
• Eliminates the need for at-grade crossings for bicycles/pedestrians connecting between the Mt. Vernon Trail and Memorial Bridge.
  
• Greatly expands the bicycle/pedestrian network in the area, utilizing some of the eliminated roads/ramps.
  
• Allows for separate bicycle/pedestrian paths along this segment of the Mt. Vernon Trail, very much needed due to heavy trail use. The bicycle path can utilize the existing northbound lanes.
  
• Allows for the possibility of a streetcar line across Memorial Bridge, connecting K Street NW at Washington Circle to the Pentagon and the proposed Arlington streetcar network.
  
• Allows for a full interchange on Route 110 connecting to both Memorial Bridge and the Iwo Jima/Marine Corps memorial (as shown on the map). Alternatively, this option could be left off and the existing congifuration along Route 110 remaining as-is.

This proposal would require a lot of money and would likely involve multiple years of construction, but the benefits of a reduced road footprint, better safety, and an expanded bike/ped network are well worth it. Even if my specific proposal isn't followed, it would be in NPS's best interests to look at a long-term solution for this area and implement it as soon as possible.

Bikes on the George Washington Parkway?

Another Dr. Gridlock column about whether the National Park Service should allow bicycles on the George Washington Parkway. Though it's in response to a reader question, it's a follow-up to a letter that WABA sent to NPS.

The argument, as it has been said, is that cyclists use the Parkway because the existing Mount Vernon Trail is crowded and inadequate, and there are no good alternative routes. While Fort Hunt Rd largely parallels the Parkway south of Alexandria, it has several issues of its own...inconsistent shoulders and pavement quality, bigger hill and curve issues than the Parkway, and the anathemia of hardcore road cyclists: traffic signals.

I'm somewhat torn on the issue. As a bicyclist, I'll be the first to say that the MVT is very inadequate and needs major improvement. As a driver, I'll echo NPS's concerns about safety...the narrow lanes, curves, and drainage issues on the segment south of Alexandria, and the limited-access nature of the Parkway north of Alexandria.

Ultimately, the limited-access nature of the Parkway north of Old Town should preclude its use for bicyclists...but this is also the most crowded segment of the MVT and the MVT really needs to be widened on this stretch. South of Old Town is more controversial and I'll admit I don't have a good solution for this segment.

I'm expecting this issue to be taken up again on TheWashCycle Blog. Look for some spirited discussion there.
