In her State of the City address Wednesday night, Mayor Lovely Warren said she wants to study filling in the northern portion of the Inner Loop. It’s not clear if she means from E. Main to N. Clinton or St. Paul or State St. It’s possible a study would explore each alternative.
There’s a reason the city decided to only fill in the eastern portion, at a cost of nearly $30 million. Traffic volumes were low between E. Main and Monroe. The cost of repairs and maintenance roughly equaled removing the highway. Land would be created in a very desirable area of the city.
The northern area of the Inner Loop is different. It’s got on and off-ramps to 490W. Many of those cars enter or leave the system at East Main St. The E. Main St. intersection has to be solved before such a project can even get off the ground.
In 2001, the city studied filling in both the eastern and northern portion of the Inner Loop. The biggest challenge to making the northern portion an at-grade boulevard was:
“…to develop an alternative that will balance the combined needs of the transportation system and the local neighborhoods. The segment of the Inner Loop from E. Main Street to North Street services a high volume of traffic and is considered a major link in the overall mobility of the area…Alternatives that consider an at-grade facility within this segment will add additional travel time and inconvenience to the existing and future users of this segment…In conclusion, the traffic analysis completed as part of the study supports an at-grade facility from Monroe Avenue to East Main Street. Based on the projected future operations from E. Main Street to North Clinton Avenue, this study suggests a grade separated facility will best accommodated the volumes within this segment.”
The recommendation was to raise the northern part of the Inner Loop, getting rid of those sloping walls that fill with trash, but keep it walled off as a highway.
In 2009, the city studied the idea again, hiring Stantec as its consultant. Here’s what filling in a part of the northern section could look like, using Scio St. as the main entry point for the Inner Loop. Stantec found there would be major traffic backups with this scenario:
Another option considered in 2009 was to drop E. Main St. below the new Union St. boulevard that is replacing the eastern part of the Inner Loop. But that would be ridiculously complicated and expensive:
Anytime you have multiple intersections like this, it’s wise to consider roundabouts. The 2009 study found you would need some double-lane roundabouts. (Rochesterians’ heads would collectively explode.) The consultants also found there isn’t enough space between roundabouts. Roundabouts also require a lot of land and there would be significant impacts on adjacent properties. The consultants also didn’t think the roundabouts could sufficiently handle traffic flow. Here’s what the roundabout solution would look like:
Stantec found the simplest thing to do to improve that E. Main St. corridor is to ‘T” University Ave., reducing the number of lights and improving flow:
The bottom line is the area is super challenging. It has a ton of traffic and physical constraints. The state agreed. A state transportation official wrote in 2009:
In point number 4, state suggested adding MORE lanes to an area that’s already a nightmare for drivers, pedestrians and cyclists. That defeats the entire purpose of getting rid of the highway. <EDIT: It’s been pointed out to me traffic volume models have changed since 2009. Induced demand is gaining more acceptance. People will just find another way to go someplace if traffic is heavy. If more capacity is added, they’ll fill it up, which doesn’t alleviate the problem. But even if you take out the issue of traffic volume, I still suspect this project will be far more costly and complex than the eastern side.)
Before we discuss whether the Inner Loop could be raised all the way to State St. (New bridge over the Genesee River, anyone?), we haven’t traveled past E. Main St. I fear this project could be $50 million to $100 million to do correctly and get any real benefits.
There’s no question our city forefathers really screwed up when they built the Inner Loop. They destroyed perfectly good neighborhoods, parks and streets. They left an ugly, trash-strewn highway in its wake. They gutted the core of our city.
We’re fixing the eastern side. But the northern side may be a lost cause. I hope I’m wrong. It’s probably worth a study that’s far more in-depth than anything done to date to find out.
