Riding from one Pittsburgh neighborhood to another can be challenging, even to those that are contiguous.

To make it easier -- and a bit safer -- Bike Pittsburgh, the Heinz Endowments and DeepLocal have teamed up to produce a new bike map of the city, the first in 15 years.

Because the Allegheny and Monongahela rivers squeeze the city into one long isosceles triangle with its top at The Point, Pittsburgh's street layout lacks the easy-to-get-around grid system of cities such as Denver.

As a result, cyclists tend to ride the larger, arterial roads where they have to share the road with speeding motorists.

The new map, as much as possible, takes them away from all that by introducing them to alternative routes via back streets that "are quite pleasant," said Scott Bricker, executive director of Bike Pittsburgh.

"Our goal is to make it simple for people to choose a bicycle to transport themselves," Bricker said.

But not all low-traffic routes are ideal alternatives for bicyclists, said Eric Boerer, Bike Pittsburgh's membership director. Some low-traffic routes are quite steep and others don't always connect neighborhoods.

"Our hills and bridges give Pittsburgh its unique identity and beautiful views, but it also makes bike travel between neighborhoods intimidating, especially if you don't know the milder side streets and how they connect to one another," Boerer said.

Bricker and Boerer said the new map contains graphic-style illustrations depicting safe commuting techniques, as well as the locations of major hills, landmarks and trails.

They said it also identifies and marks unavoidable stretches of road that are hazardous.

In conjunction with Bike Pittsburgh's mission to establish Pittsburgh "as a city that is increasingly safe, accessible and friendly to bicycle transportation," the map also provides information on who to contact to lobby for safer streets.

The new map was created by Bike Pittsburgh and funded by the Heinz Endowments.

Nathan Martin of DeepLocal was the designer and cartographer. Glen Johnson of DeepLocal did the illustrations.

A free, open-to-the-public "launch" party for the new map will be from 6-10 p.m., Nov. 2 at the Edge Studio, 5411 Penn Ave., Garfield.

It will contain displays of the map from its early stages to the finished product.

Snacks and beverages will be provided. And maps, of course.

The maps also will be available at various locations around town.

Short but sweet

The Montour Trail Council will hold a brief groundbreaking ceremony at 10 a.m. today for the construction and rehabilitation of three bridges on the Montour Trail in west Peters Township.

Council president Mark Imgrund said the bridge work, along with approximately 1.8 miles of trail and one tunnel, will connect the 29 miles of completed Montour Trail extending from Cecil Township to Coraopolis to within about 200 yards of the nearly 9 miles of already open trail in Peters and Bethel Park.

Imgrund said the ceremony will be on the future trail, a short walk from the parking lot of TAR Outside Storage on Valleybrook Road.

To get to the ceremony, take Valleybrook Road west from Route 19 (turn right at the bottom of the ramp off Route 19) and go about a half mile to the TAR entrance to the right.

Imgrund said refreshments will be served at Cecil Park after the ceremony. For more information, go to www.montourtrail.org, e-mail info@montourtrail.org or call 412.257.3011.
