The construction of six shelters at bus stops in Downtown Boise has inconvenienced motorists, but Valley Regional Transit should finish the work in about a month, a spokesman for the organization said Friday. The shelter projects on State, Main and Idaho streets are part of a Valley Regional Transit push to enhance bus stops across Ada County this year. Other improvements include making bus stops more easily accessible to disabled people, spokesman Mark Carnopis said. Last year, Valley Regional Transit spent more than $1 million building and improving bus stops in Ada and Canyon counties. This year, the organization is slated to spend $1.275 million on the six downtown shelters, 152 bus stops in Ada County and the purchase of 39 other shelters, according to information received from capital infrastructure project manager Rhonda Jalbert. Much of the work has been funded by federal stimulus money.
