The Norris Bridge Painting Project has begun in Full this month.
Sitting on the Bridge waiting for the signal to change really hit home on several points:
How many other times in the last 25 years has the Norris Bridge provided "Limited Service" due to being a construction site ?
Limited Service on the Norris Bridge due to:
The chart above is a summary of VDOT related activity on the Norris Bridge.
This accounting does not include days for wind/weather related closures [N'or Easter or hurricane] and does not include days when VDOT work was not performed due to holidays and reasonable allowances for seasonal weather delays.
The information above is drawn from VDOT and newspaper archives.
This chart is a conservative representation of the instances gathered; it is by no means complete.
I am sure there was work done 1997-2006 too, but I did not show anything for these years because I could find no data.
FREEDOM of INFORMATION ACT [FOIA]
I would send a FOIA request for information to VDOT asking to receive an itemization of # days traffic on the Norris Bridge was affected by VDOT activities but I am still waiting on clarifications to the conflicting summary of costs for bridge construction & maintenance activities for the Norris Bridge since 1985. I sent a FOIA in September and received conflicting reports from VDOT in January and again in March.

In the May 2016 Route 3 Transit Study VDOT describes the
Level of Service on the Norris Bridge as "Unstable" based on a census done 2012:
E: unstable flow, operating at capacity. Flow becomes irregular and speed varies rapidly because there are virtually no usable gaps to maneuver in the traffic and speeds rarely reach the posted limit. Any disruption to traffic flow will create a shock wave affecting traffic upstream. Any incident will create serious delays. Drivers level of comfort becomes poor.
This rating is based upon the typical daily flow of traffic and does not account for "construction or maintenance" impact on traffic. The "Unstable" rating is actually worse in light of the proportion of time the bridge has limited service while being "maintained."
According to the Highway Capacity Manual (HCM) with A being the best and F being the worst, similar to academic grading the Norris bridge is reflective of:
F: forced or breakdown flow. Every vehicle moves in lockstep with the vehicle in front of it, with frequent slowing required. Travel time cannot be predicted, with generally more demand than capacity. A road in a constant traffic jam is at this LOS, because LOS is an average or typical service rather than a constant state. For example, a highway might be at LOS D for the AM peak hour, but have traffic consistent with LOS C some days, LOS E or F others, and come to a halt once every few weeks.
How does the "Unstable", Functionally Obsolete, 60 year old Robert O. Norris Bridge serve as a tool for Economic Development on the Northern Neck ?
